There are two items noticeably missing from Tex-Mex joint Buster's Burritos: tacky souvenirs from across the border and lumpy, pastelike refried beans. Instead, the setting is minimal, but not sterile or institutional, and the giant burritos, tacos and chimichangas are served with whole black beans sprinkled with a fetalike cheese (they call it a Mexican version of Parmesan) and accompanied by a dollop of pico de gallo. Just like everything at Buster's, the beans are a nice diversion from standard fare.
