Well, this restaurant is pretty famous among those who drink in Shinjuku. The location is a bit sketchy, so it might seem intimidating at first, but the restaurant itself is pretty normal. The interior is like a cave, with a counter, private rooms, and table seats. It's interesting how the food is served directly from the kitchen. Speaking of interesting setups, they offer all-you-can-drink options. You can drink for 1 hour for 1500 yen, or 3 hours for 2000 yen, which is quite reasonable. And despite the affordable drinks, the food is focused on seafood and is actually good quality. It's said to be the place to go for fish in this area. It's also nice that they're open 24 hours for a casual visit. I'll definitely come back again.

I visited "Kenshin-ryu," which I have relied on many times in the past, after a long time. Located on the second floor of the Lee3 Building on the outskirts of Kabukicho, on the Kuyakusho Street, it is like a hidden gem nestled in the entertainment district with host clubs and love hotels. It used to be open 24 hours, but now it seems to be open from 12 pm to 6 am due to the COVID-19 pandemic. The menu is mainly Japanese cuisine and quite delicious. What's more, they offer an all-you-can-drink course with a variety of drinks from sake to wine at unique prices! (1 hour for 1500 yen, 2 hours for 1800 yen, 3 hours for 2000 yen). It used to be cheaper, but the crazy system where the more you drink, the cheaper it gets is still interesting (laughs). It seems to be popular among people working at night who come for an after-work drink, as well as familiar couples from love hotels nearby. The place has a strong presence, and if you bring someone here for the first time, they are sure to go from "What is this place!?" to "Scary" to "Interesting"! If you feel like having a drink during the day with a good friend, this is highly recommended in Shinjuku.

I went to Kenjinryu for the first time in a long time for a year-end party with friends. The atmosphere hasn't changed at all, even though I've been going there for decades. The all-you-can-drink option was great, and the alcohol was of good quality for an all-you-can-drink deal. It's a great place for people who want to eat a lot and drink a lot. If you haven't been there, I recommend giving it a try.

A shop located in the host club district. It is on the 2nd floor of a building with many host clubs. Upon entering, there are a few private rooms at the counter. The atmosphere inside is calm and not noisy, which is rare in Kabukicho. It's a very nice shop. We ordered a 2-hour all-you-can-drink option, starting with draft beer. We also ordered some appetizers. The drinks were served quickly and the appetizers were delicious. It's a really nice place. I will visit again. Thank you for the meal.

All-you-can-drink is recommended. 3 hours of all-you-can-drink for 2000 yen. You have to order at least 2 dishes per person for food. There might have been a cover charge. The food was delicious. It's a bit hard to find in a mixed-use building in Kabukicho, but it's a place you'll want to go back to. The emotionless service is very Shinjuku-like.

A dimly lit private room izakaya that is open 24 hours a day, no matter the season. I have been coming here for 30 years. Three hours of all-you-can-drink for 2,000 yen! Order at least two food items. They have a variety of Japanese dishes starting from 400 yen. In these times, when you want to drink with three people late at night, this is the place to go! I made a reservation and we drank non-stop. After 1 am, we went to an even deeper bar with steep stairs! If you can tell from this picture, you must be a regular!

This is a great restaurant with thorough COVID-19 measures in place, making it stand out from other nearby izakayas. The food is delicious and the all-you-can-drink option is very affordable. As a regular customer, you receive special treatment from the staff, which adds to the enjoyment of visiting this nostalgic restaurant.

I used it for a company dinner. They are very thorough with their COVID-19 measures, so you can use it with peace of mind. Since I had requested in advance, ordering additional dishes was smooth. The all-you-can-drink option is quite reasonable. The staff are attentive and the service is excellent. I look forward to using it again.

My colleagues and I are in agreement. The COVID-19 measures are perfect. The staff are wearing masks and face shields, providing a sense of security for us. The food is consistently delicious, with generous portions and great presentation. The private rooms make it a recommended choice even during this time.

Shinjuku's hidden gem izakaya! The interior is unique, with tables along the aisle and a few private rooms in the back. The atmosphere is dimly lit. The all-you-can-drink option is affordable at 1300 yen for 2 hours per person. The menu is extensive with dishes like chilled tomatoes, stir-fried green peppers, sashimi, shiitake mushrooms, and rolled omelette. The stir-fried green peppers were particularly delicious! The sashimi was a bit disappointing as it was on the softer side. There are many menu items that pair well with drinks, making it easy to keep the drinks flowing.

I used it for a reception. The COVID-19 measures are perfect. I think you can enjoy your meal with peace of mind. The taste is consistently delicious, and the service is speedy without any stress. It's a wonderful response in such a place at such a time.

Kabukicho is interesting, isn't it? From dentists, hosts, and hostess clubs to gay bars and back alley Chinese restaurants. I used to hang out a lot around the age of 30 (lol). I heard the owner also runs a host club. Either way, the owner is smart. Sometimes hosts and hostesses want to eat healthy food, but there aren't many Japanese restaurants above a certain level where they can just drop in after work. So, they opened a restaurant to meet that need. It's open 24 hours, but it's always fully booked during prime time. The staff with dyed hair and lots of piercings bring out delicious Japanese food and perfectly poured draft beer. The food uses carefully made dashi, making it much tastier and more satisfying than chain izakayas. The location, taste, price, and 24-hour operation style are impressive! It's a very popular restaurant, so you need to make a reservation 1-2 weeks in advance. If you have plans in Shinjuku with friends or a girlfriend, I think taking them to this restaurant is great, especially in the summer. Of course, you need to plan whether you'll go to a bar, gay bar, or hostess club afterwards (lol). If you can do that, you can fully enjoy an extraordinary drinking experience in Kabukicho. Highly recommended for men in their 20s to early 30s who want to drink well. Also great for dates or girls' nights out. Just for private occasions!

This is a 24-hour izakaya in Kabukicho. The prices for 1-hour, 2-hour, and 3-hour all-you-can-drink are only a few hundred yen apart, so we opted for the 3-hour course (cannot change midway). The rule is to order at least 2 dishes per person when ordering the 3-hour course, so we had a daytime drinking party following that rule. The menu includes a variety of dishes like sashimi, fried foods, grilled items, and more. While it may not be worth going out of your way to visit during peak hours, it's a great option for drinking at odd times.

The other day, I had plans to drink in Shinjuku and was wondering where to go. I had been curious about this izakaya for a while. It is located on Kuyakusho Street and is open 24 hours! The dashimaki tamago was fluffy and very delicious! The pork taccarbi was flavorful and good! I will definitely visit again!

It is located near the Furin Kaikan in Kabukicho. The interior of the restaurant has both counter and table seats, but it is a bit small. The menu is quite reasonably priced with a wide variety of options. The sashimi assortment is fresh and delicious. The pork toro with ponzu sauce is a good appetizer. The taco rice is also tasty, and everything we ordered was delicious. They are open until morning, so I would like to visit again. Thank you for the meal.

The food is a bit pricey, but the all-you-can-drink alcohol for 2 hours is around 1300 yen, which is cheap. The building has a deep atmosphere, and all the dishes are delicious with no misses. Particularly, the potato salad, braised pork, and sashimi were good. I'm curious about the tuna hamburger as well.

After leaving Kabukicho and entering a building with many night establishments, I felt nervous due to the unfamiliarity at first. The location adds to the hidden gem vibe, as it's not easy to find unless you know about it. What surprised me was that they are open 24 hours! Besides sashimi, we also tried pork taku and simmered pork, but the sashimi and soft-boiled egg with the simmered pork were particularly delicious.

In a mixed-use building, I found a shop that took me a little while to locate at first. It was deserted in the middle of the day, so I ordered the 1-hour all-you-can-drink for 1300 yen and some dishes. The dishes, such as simmered turban shell, live surf clam sashimi, chilled tomatoes, and beef steak, came out quickly. The food was delicious and well-prepared. The turban shell was particularly tasty, and the surf clam was fresh. I enjoyed about 4-5 drinks as well. It's a good place to visit during the day when it's not crowded. Since it's open 24 hours, it's a great spot for a meal. Thank you for the wonderful meal!

Located in a mixed-use building in Kabukicho, "Kenshinryu" is open 24 hours a day. I have tried visiting the restaurant at night several times, but it was always full. So, when I had the opportunity to go to Kabukicho during the day, I decided to try my luck on a Sunday afternoon, and this time I was able to get a table. The interior of the restaurant has counter seats and table seats in the back, with private rooms. This time, I chose a table seat at the back, which allowed me to peek into the kitchen and see the counter seats through the window, giving a sense of secrecy. The ordering system offers all-you-can-drink options for 1 hour (1300 yen) to 3 hours (1900 yen), with a set number of dishes to order for each time limit, following their unique rules. Single drink orders are priced at 500 yen per drink, and I ordered two dishes. Although the 3-hour all-you-can-drink option seemed enticing with its wide variety of drinks, since it was lunchtime, I decided to go with single orders this time. The menu offers a wide variety of dishes, and I had a hard time choosing, but eventually settled on the grilled bamboo shoot with seaweed miso, potato salad, minced raw fish, mountain yam with raw egg, and stir-fried pork belly with pickled daikon. Each dish was carefully crafted and exceeded my expectations, making it easy to keep drinking. I started with a glass of draft beer, then switched to a tasting set of three types of sake for my second drink. The dimly lit atmosphere of the restaurant made me forget it was daytime, and I found myself enjoying the drinks more than I intended. Perhaps I should have gone for the all-you-can-drink option after all (laughs). I also learned that there is another restaurant called "Kenshinryu Shun" on the 8th floor of the same building, and upon asking a friend who enjoys drinking in Shinjuku, I found out that if the 2nd-floor Kenshinryu is full, they will guide you to the one on the 8th floor. I definitely want to visit the one on the 8th floor as well.

I have visited this restaurant countless times. They offer all-you-can-drink including draft beer, and they have 5 types of dry sake, which I think is a great deal. I usually never go to all-you-can-drink places, but I like the variety of dishes they offer. My favorite is the sashimi, which is always fresh. They also serve delicious seasonal mountain vegetables like bamboo shoots and butterbur, as well as grilled fish that I wouldn't normally eat at other restaurants. It's a shame that the clientele has gotten younger in recent years. It's probably because it's affordable and accessible to young people. The atmosphere of the restaurant is calm, but the clientele sometimes disrupts that atmosphere. I don't expect much in terms of service or hospitality from this restaurant, so I don't mind that aspect. I just hope that the kitchen staff's quality and skills remain consistent. The fact that they are open 24 hours is convenient, but because of that, the staff turnover is high, so it's understandable.
