Open 24 hours, this fun little restaurant is a good choice for seafood lovers. There is a wide range of offerings, including sashimi, donburi, and seafood grilled at the table. Enjoy them with Japanese drinks such as shochu, sake, or beer.
There is a lunch menu featuring mostly donburi rice bowls with seafood, it is offered from 11 am to 5 pm. Seating is crowded at low tables with cushions, so this is not a good choice for people who have difficulty with mobility. Children are not encouraged. The Ueno Isomaru restaurant is located on Nakamachi Street across from Shinobazu Pond in Ueno Park. There are around 50 locations around Japan, so you may see it on your journeys!
