My family chanced upon Casa Fiesta last year while driving home from a vacation. The service has been fantastic, friendly and prompt every time we've been there. Portions are huge, so come with an appetite (or at least a pal to share an entree with), and are quite delicious. The prices are good, especially considering you basically are getting at least 2 servings with your entrees.
Definitely a must-stop when we go through BG from now on!
