We stopped there last year and had lunch at a restaurant called La Panza es Primero. It was a recommendation from a local and it didn't disappoint! I will admit, had I just read about it in a guidebook, I would have kept on walking. It has a wrestling theme - you know, like WWF or whatever that is. But actually that added to its charm. The food was simply to die for. Authentic, delicious all the way! Margaritas were fresh (no canned mixers) and the service was outstanding. We're planning a trip back to PM from the hotel zone just to eat there again. Definitely give it a try!
