Madrid-Barcelona
So named because it was formerly a traveler's bar when the trains used to pass in front of it. This is a very convenient restaurant for three reasons: It's very close toLa Pedrera and the other monuments in Passeig de Grà cia, it serves good and quite typical food in a place with history, and the prices are very moderate for the zone where is located. Some dishes are fried things, such as pescadito frito. Large servings of seafood mussles, snails; the main course with chicken looks promising.
