This restaurant, right in the Chueca neighborhood, is one of the best Mexican restaurants you can go to in Madrid. It is usually packed, thanks to the nice decoration, good service and stunning quality of dishes.
I usually don't really like Mexican food because it is too fat and too little elaborated to me. In "La panza es primero" forget about this! It is not that Mexican dishes are bad, but we are more used to have what is called Mexican "fast food", very different from the flower chicken, cactus tacos or guacamole nachos you can get in this restaurant. Really delightful! The menu only has Tex-Mex food from the North of Mexico (more based on meat than in the South).
