I've been twice. First time was really good, second was not.
Ordered the chicken carne burrito both times; first time was loaded with nothing but shredded chicken and guac - perfect, second time it was a 4oz portion of grilled chicken in a 12" tortilla - not good. First time the Corona Light (on special) was cold and very fresh, second time it was barely cold, no head and stale.
(5+2)/2= 3 stars, rounding down. We'll go again and I'm hopeful for a repeat of the 5-star.
