Arzak
One of the world's great culinary meccas, award-winning Arzak embodies the prestige, novelty, and science-driven creativity of the Basque culinary zeitgeist. The restaurant and its high-tech food lab—both helmed by founder Juan Mari Arzak's daughter Elena—are in the family's 19th-century home on the outskirts of San Sebastián. The ever-changing dishes (€270 for four courses or €300 for the tasting menu) are downright thrilling for their eye-popping presentations, unexpected flavor combinations, and rare ingredients. The best seats in the house are in the newly renovated upstairs dining room.
