Sant Pere Specialty

This busy, beloved cava spot, best known as La Xampanyeria (also called Can Paixano), is tucked on a side street where a few neighborhoods—Gothic Quarter, La Barceloneta, and Sant Pere, Santa Caterina i la Ribera—meet, within walking distance of Muse Picasso. It's fun and lively, and you can soak up some of the champagne with a sampling of the bocadillos on offer.

A major Spanish wine distributor, Vila Viniteca opened in 1932 and is now a third generation family-run business. For a really good selection of both local and international wines, head to their shop on Agullers. And, FYI, if you're looking to pick up food as well, Vila Viniteca's gourmet grocery store, which stocks small bites, cheeses, and cooked meats, is conveniently located next door. (Also to note: Vilia Vinetca has another, smaller wine outpost in the shopping mall, L'illa Diagonal.)
