Border Cafe may not offer the best Mexican food in town, but serves the best margaritas. Maybe that is why patrons do not seem to mind the wait that is often well over an hour on weekends. A party atmosphere rules here; many of the diners are college students and exuberant tourists. Portions are giant and cheap. Favorites include zesty, fizzling fajitas and popcorn shrimp. This is a good choice for a large party.
