L'Oveja Negra can be called a 'sangria transfusion station'. Here they will make sure that even a light drinker is leaving the bar tipsy. As far as I know, the place is closed during day hours and opens only after 7 p.m. As for the décor, you will see huge wooden tables, a pool table, college students, waiters and dim lights. Visitors are diverse but the spot is popular with Barcelonians. Here sangria is sold by liters, is as cheap as chips and you are guaranteed to have fun the whole night.
