First of all, it's not a completely private room. There are partitions like sliding doors, and the seats are cramped, designed to fit in as many customers as possible. Some seats may not be suitable for larger people. It could also be due to the fact that I went on a Friday when it was crowded, but because of the sliding doors, the voices of noisy young customers are not completely blocked, making it difficult to hear each other's conversations. Also, the all-you-can-drink option does not include draft beer, and they try to recommend the premium all-you-can-drink option. Some of the staff are foreigners, so be prepared for possible communication issues. The number of seats and the number of toilets do not match, so be prepared to wait in line. Also, since they renovated an old building, the elevator is small and may only fit 5 people. This could lead to a bottleneck of customers waiting from the first floor to get to the elevator on the second floor. Additionally, ordering for the all-you-can-drink option is now done through QR code scanning, which is becoming more common. The food itself was decent in my opinion, so it's a shame that these issues stood out. Disappointing.

I recently visited a new restaurant in Shinagawa. All seats are in private rooms, which I found very appealing. There were 7 of us, so we were guided to a private room with a sunken hearth. We decided to try their specialty beef tongue dishes, such as boiled tongue, beef tongue carpaccio, beef tongue tempura, beef tongue with garlic ponzu sauce, and beef tongue shabu-shabu, and they were all delicious. I highly recommend it for beef tongue lovers. The atmosphere was also great. I found out online that they offer a 3-hour all-you-can-drink course, so I will definitely consider using it for a company party. Thank you for the wonderful meal.

We made a reservation for a 3-hour, 5,000 yen course for 8 people at a nice restaurant for a gathering with some teachers. The private room had a traditional Japanese feel with sliding doors around the booth seating. The doors stayed open most of the time due to ordering. The seating was a bit small and felt cramped for some tall guests. The food was delicious and had good portions. The only downside was the beer selection, so we upgraded for an additional 500 yen. Despite it being a Tuesday, the restaurant was busy and had a lively atmosphere with young staff. Overall, it was a great choice and we had a wonderful time. Thank you for the lovely meal!

All-you-can-drink with a limit of two items per person. The volume seems a bit lacking for the price.

The food is delicious! The portion size is amazing! However, the seats are narrow and when all the dishes are brought out at once, they tend to get cold, which is disappointing. I will probably go back again though.
