The full realization of your foreignness as a visitor is realized here, and that's okay. We needed…read morea quick, cheap lunch before hopping on the train, so we stopped in based on a recommendation of local spots. Everyone is either sitting at the semi-circle bar or standing along the small counters on the walls.
We ordered in Spanglish, everyone in the room turning to listen.
Service is direct and functional, but not uncomfortable per se. The bocadillos are varied, simple, and affordable. We had the artichoke, chorizo, and San Francisco (pork, cheese, tomato -- if I can recall correctly). Some of them come with mayo, and it comes heavy, but it's a fluffy mayo. We added a beer, ate standing, and went along our way.
