Operating since 1947 in the old town, Juanito Kojua is the kind of seafood restaurant that exists because the port is close and the traditions run deep. Grilled turbot, hake in green sauce, marmitako — the menu reads like a textbook of Basque maritime cooking, except here every dish carries the accumulated wisdom of nearly eight decades of service. The wood-panelled room smells of the sea and charcoal.

Insider Intel
The grilled turbot is the benchmark — order it and understand why Basque fish cookery needs nothing more than heat and salt. Marmitako (tuna and potato stew) when in season. Hake in salsa verde. The merluza a la plancha. Simple preparations that expose quality.
Lunch for the freshest catch. The dining room fills by 1:30pm on weekends — arrive early or book. Tuesday through Saturday for the full range.
Nearly 80 years in the same location tells you what you need to know about consistency. This is not a restaurant that reinvents itself — it refines what it has always done. The seafood is sourced from the Cantabrian coast and the preparations are classical Basque. Portions are generous. The wine list is Basque-focused with good txakoli options. No pretension, just decades of accumulated skill.
