I love Madrid (used to live there and would move back in a minute) but could use a little refresher on the best places for tapas. I'll be in town for two nights (from a Friday-Sunday) with two close friends. We'd like to spend one evening wandering from one tapas establishment to the next. Ideally we could also find a balance between Madrid specialties, Asturian and Galacian places and a few Andalucian offerings. Any suggestions? I have been to Calle Alta/Brava before but cannot remember specific places there. Would be up for any part of the city though we're staying near the Plaza Mayor.
Thanks in advance!
