One good option for nightlife is Pepe's Bodega, Warmbadhuset Hamnen (tel. 0431/36-91-69), where spicy food and festive cocktails evoke southern Spain, northern Mexico, or some undefined hideaway in a forgotten corner of South America. It's open Wednesday to Sunday both for food and for its active bar life (from 5-11pm for food, and until 1am for drinks). There's also an on-site disco.
