We went to El Patron a week ago for lunch on a Sunday. The service was very good, our server made sure we had plenty of chips and salsa on hand and kept our drinks filled.
Our food was hot and fresh.
My only complaint is that with a chicken chimi you only get beans, not beans and rice that other Mexican restaurants serve.
I feel that the service is better here than at Los Tres Amigos where they sometimes don't understand your order.
