Most of the lodges and hotels are package deals with meals included (something like, 3 nights and 4 days full board). So, most likely you will end up eating at the restaurant where you are sleeping.
Food is basic, but enough to stick to your ribs and keep you happy. Expect fish preceded by fish soup.
There are a couple of options in the town. The restaurant at the Hotel Valle is a roast chicken place, which also doubles as a bakery.
Nightlife
Nightlife in the area appears to be next to non-existent, aside from settling down for a few beers with the locals. Although, this is not always an option as the town has been known to run out of beers when the roads are closed and supplies can’t get through.
