Ryutan is an izakaya in Okinawa that serves dishes such as beef tongue and mackerel. Its main items include aburi-yaki beef tongue, vinegared mackerel, and rafute, with a range that covers light snacks through full meals. The seating consists of dodge tables and four-person tables, and the menu is hard to read, so staff have to be asked; reservations are frequent, so booking through the website is required. The venue allows smoking, which makes it uncomfortable for non-smokers.
