This town is very subdued at night. Because most visitors rise at the crack of dawn to head to the Península Valdés, Puerto Madryn shuts down early. The best place for a late-night drink (and light snacks such as pizza and hamburgers for $5-$9/£3.40-£6.10, served until 1am) is Margarita Pub, R.S. Peña 15 (tel. 2965/450454; daily 5pm-3am; no credit cards), an attractive wood-and-tile lounge with a large bar. All the locals who work as guides during the day come here on weekends -- this place is hopping from midnight to 3am on Friday and Saturday.
