We’ve been at the Plaza Mayor a few times and have never been disappointed. Usually we start the evening with Red Sangria and order the Jamon Iberico Bellota, Patatas Bravos, Croquetas de Jamon, Chorizo and the Pulpo a la Gallega, amongst others. Once the dishes arrive, we’ve a good bottle of red wine, usually the Avan. All in all, and you can spend a very nice evening there. Staff is very friendly and all very reasonable priced. Very good value for money

Tonight my wife and I ate here for 5th time in a year. Nobody ever makes any effort to notice us or welcome us back. Service is always indifferent and inflexible. Tonight we sent a dish back for being undercooked, and the senior guy (manager? owner? all around jerk?) came to our table to give us a LECTURE on how the dish was not undercooked, and how we obviously don't understand "Madrid cuisine". Last thing we needed while trying to relax on Sunday night before start of a long week. No offer to re-do the dish, or to "comp" it. We will not go back.
