I've been searching through past posts and I see far more recs for restaurants than for tapas bars. We travel to Spain frequently and will have 2 nights to eat tapas in Madrid before heading to Basque Country. I've not tried any of the places in Retiro that someone mentioned but I've bookmarked that post and will try them out. We have enjoyed the energy in Chueca and could use some recs for that area and we are staying at Roommate Mario. Any help would be greatly appreciated and I'll keep reading through old posts in the meantime.
We'd like to keep this part of the trip pretty traditional in terms of food so the simpler the better.
Thanks in advance for your help.
