There are 3 locations of Pancho Villa: one at the corner of 17th and Valencia, One near Pier 1 and another in San Mateo.

This is a good mexican restaurant with good food that cuts to the chase. Like 99% of mexican restaurants, if you're expecting super nice service, or people smiling, etc. Forget it. Go to Chevy's or something...then again, that's not mexican food.

Everything is pretty good, mostly their quesadillas and shrimp burritos. They're pretty huge too and are more than worth the price. Make sure you get some Aguas Frescas (my wife's favorite). Food is fast and furious. Go there when hungry....especially if you're near San Mateo.
