Started by two college students, BTB Cantina is a counter-service restaurant that services price-sensitive students as well as diners scavenging for a quick bite. The burritos make a large part of the default orders here, as does the deep-fried grilled chicken chimichanga served with guacamole, salsa, and an extra helping of cheese. It's a substantial carbo load to support students through late night study sessions, or through an evening sipping on margaritas at the bar.
