Although I have far from tried all of NYC'S mexican food, this is by far the best. It's just that good. There are a few locations, but the one on the UWS is the best for some reason. I'm pushing full by the time I get done with their made-in-front-of-you guac. It fascinates me how they cut and peel an avocado in <5 seconds.
They are so great about us bringing the boys. Last time they set us at a table for 4 and put the car seats up on a booster chair.
Online pics make the place look far more sleek than my phone can capture.
