Since 1974, Pepe Ortiz has personally hand-picked seafood from La Almadraba market each morning. At this unassuming Nervión tavern, he cooks cigalas and quisquillas with surgical precision while his wife Dolores turns out immaculate fried hake and filetitos al güisqui in the back. No printed menu: just two blackboards and whatever was freshest that day.
