TETSU is a basement seafood restaurant two to four minutes from Akihabara Station. At lunch it serves a seafood rice bowl topped with 15 to 17 kinds of fish and seafood, along with soup and misoshiru. Dinner is reservation-only course service, and the lunch seafood bowl is limited to 10 servings per day. Seating is just 6 counter seats and 18 floor seats, so lunch space is limited.
