We are going to be in Madrid for three days in Mid-March and have never been to Spain before. We have been reading about all the Tapas bars and are overwhelmed by the number of places. I would appreciate advice on the best to go to for an authentic experience. Also would appreciate restaurant advice for traditional cuisine. Whatever is the Spanish equivalent of a bistro would be my preferred restaurant style--not too formal. We are staying at The Palace Hotel so recommendations in that area would be great. Thanks for your help!
