Arzak

When it comes to fancy multi-course meals, you won’t find a better option in San Sebastián than Arzak. This restaurant is where the Basque cooking movement of the ‘70s, nueva cocina vasca, started, which basically makes it the hub of fine dining in Spain. The tasting menu reads like a greatest hits list of Basque cuisine—the Arzak team thrives on innovating local dishes and produce, which means you’ll find things like beef cheek in a jet-black sesame sauce and razor clams paired with tomato gel and green mayo. The meal will cost you around €300, but this is a once-in-a-lifetime experience, so sit back, pick something from the 100,000-bottle wine cellar, and enjoy your foie cromlech and the marbled egg.
