PerretxiCo

This award-winning spot packs in the crowds with inspired bites such as octopus and sweet potato tacos, codfish tempura, and goat's-cheese, walnut and honey lollipops. For something more substantial, book a table in the back and linger over roasted whole turbot with mushrooms, or roast Navarran lamb with yellow-pepper relish. Until noon, it serves house-made churros and hot chocolate.
