Mercat de la Barceloneta

"If you’re looking for a market near the beach, this is as close as it gets. Situated in Barceloneta, formerly home to the city’s fishermen (many of whom can no longer afford to live there), the building is modern and covered in solar panels. The market was initially formed to keep the fishermen and their families supplied with fruit, vegetables, and the catch of the day. Perhaps because of its origins, it’s the most budget-friendly on this list. At Mercat de la Barceloneta, the menús del día at bars and restaurants start at 12 euros ($14). Nosh on bombas (deep-fried mashed potato balls stuffed with spicy sauce and meat) that are almost as good as the ones from La Cova Fumada, the Barceloneta bar where the bomba is said to have been invented. Or, nibble oxtail croquetes and smoked anchovies in fresh tomato and olive oil sauce on the terrace at Marisma." - Chris Ciolli
