Thank you for the advice. I actually already have Mariscos Polo on my list; I have the address Fran Madero 376. We always eat at the other place too, on Iturbide y Miramar, as it is just down the street from the house where we are staying. They know us so well now, we go there and order the food, and they deliver it to our front door 20 minutes later!! We enjoy calamari, Spanish tortilla, and chicken skewers with fresh bread and aioli! Goes down nicely with a margarita, while watching the sunset!
