Despite its name, this isn't a place aimed specifically at the bear community (os in Catalan and oso in Spanish mean 'bear' in English). This particular Os refers to the owner, Óscar Verde. Opened in November 2012, it has generous opening hours that make it worth a look almost any time of the day. Daily from 8am you can enjoy breakfast there, or a mid-morning coffee, lunch or afternoon snack. During the week, it's open until 11pm, Thursdays until midnight, and Friday and Saturday until 3am; Sunday is a much-deserved day of rest. As well as a place for food and drink, they host art exhibitions by up-and-coming creatives, and you might also catch an afternoon session of board games in English.
