Of course it doesn't help that we fill up so much on the chips and salsa!
while it has been a long time since I went to one of these places I always would tell myself that I am not going to load up on chips and salsa, but I always do and this is even though it normally only takes 5 minutes, miraculously, for all mexican food to be prepared.
I have never been offered free chips and salsa in any restaurant in Mexico.
