If you work up an appetite looking at the fresh meats, fish, produce, cheeses, and more in El Mercado Fontán, there’s a simple solution. Climb the stairs to market restaurant, El Fontán, for hearty home cooking in a lively room overlooking the main floor of the 1885 market hall. There’s a daily menu that is a super-bargain as it includes a half-bottle of wine. Market workers swear by the restaurant’s pote Asturiana, a stew of white beans (of course), potatoes, assorted sausage, and shredded kale with a hambone tossed in for seasoning.
