Izakayas are like Japanese gastropubs, and Uoshin is a traditional izakaya and a great introduction to Japanese cuisine. This place specializes in fresh seafood from all around Japan, so you’ll want to try different fresh, grilled and boiled fish dishes. The nitsuke boiled fish dishes are stewed in a hot pot of soy sauce, sake and some sugar and ginger. If you just landed in Tokyo and have no idea what you’re doing food-wise, this is a good way to ease yourself into things and get a feel for what you’ll eat on your trip.
