Went to the Elkhart, IN location on a Monday night in late December with a group of 9 in town for a funeral. The place was surprising busy - we waited for more than half an hour. The service was spotty - the waitress was friendly, but brought the wrong number of waters, didn't salt the margarita glass as requested, forgot to put tomato in the guacamole. (She told us it was only the third time she'd made guacamole.) Portions were huge - the small burrito was the size of a dinner plate and was smothered in cheese, probably not the "under 600 calories" billed on the menu.
