Fodor's Expert Review Bar Tomás de Sarrià

Famous for its patatas bravas amb allioli (potatoes with fiery hot sauce and allioli, an emulsion of crushed garlic and olive oil), accompanied by freezing mugs of San Miguel beer, this old-fashioned Sarrià classic is worth seeking out. You'll have to elbow your way to a tiny table and shout to be heard over the hubbub, but the effort is richly rewarding.
