Hachioji, Tokyo, Japan｜Genuine Izakaya Diner "Uotami" Keio Hachioji I-Road

It's an izakaya. The inside of the restaurant is mostly tatami rooms (horizontal kotatsu), so groups of about 30 people are welcome (reservations required). Rooms are either curtain partitioned or private rooms. The store staff responded fairly kindly.

You can rest assured

Almost all seats are private rooms and clean. Customer service was good. I used to shy away from it, but I think I'll use it in the future.
