Barcelona's brew pubs are fun, exciting and always feature delicious cervezas (beers). From the Irish pubs to the Belgium ones, the city hosts a wide range of pubs, all with a Spanish/Mediterranean edge. On Via Laietana in the Old City there are several Irish pubs usually featuring Irish Brews such as Stouts and great draft beer. Barceloneta also has a fair amount of Irish pubs all of which are excellent places to watch the football games, especially during the World or European Cups.
In Gracia Neighborhood, there are some lively Belgium Brew Pubs, all of which are very local with a mix of expats as well as Catalans who enjoy Belgian beer. Most of the brew pubs play live music, so be sure to check out the schedule online or at the bar, to see which band is lined up.
The pubs in Barcelona are a refreshing alternative to the tapas and wine bars. They usually attract a more touristy crowd, especially during holidays like St. Patty's Day which is more of a North American and Irish affair. Although more and more Catalans and Barcelona expats are starting to frequent the pubs and choose a cold beer in addition to or even sometimes instead of, a glass of Rioja or Ribera del Duero.
