Visited in Oct 2006. Got in before 6PM, before leaving, the wait line had 10+ people in it (most of the tables being filled)
Being a first visit, the family got a basic selection off the menu (enchillada plate, taco/burrito plate, nachos grande). All were on the high side of our spiciness quotient, but not unbearably so.
Considering the time of day, and the crowd, the staff was attentive and the food was only slightly delayed.
