Fat Bastard's is okay, considering the limiting choices near St. George campus. It's a good place to fix your burrito craving.
The small burrito was enough for lunch... you have been warned. I got the tequila lime chicken (fried, of course), and it was fantastic. Loved it. The first scoop of guacamole is free. However, the service wasn't exactly polite. And I really didn't mean to, but I looked up and saw the lamps. The dusty lamps. Right above the (unprotected) food. Best not to think about that when you're enjoying your burrito.
