Fūmu

A sushi bar steps from Gijón's marina, where the counter seats eight and the fish is aged in-house, which is the kind of detail that tends to separate the committed from the casual. The menu is compact, Japanese in its bones but built around the catch from the Bay of Biscay, with nigiris given serious attention and an omakase format designed for sharing. It skews young and informal without being careless about it.
