If you like fishing, seafood, and interesting places, there is a restaurant called Zauo where you will want to dine at. The one we went to is on the first floor of the Washington Hotel in Shinjuku near the Tokyo City Hall. You can rent a fishing pole to catch a fish and then they will cook it for you. Your table is on a boat and you can watch over other people fishing while eating your food. Other than that they have this fishing pool inside of the restaurant, it looks like a normal Izakaya for people to enjoy food and drinks though.
