The character Steve (played by Dustin Doering) mentions a chance to win dinner for two - possibly even at Luby's. Luby's Cafeteria is a chain buffet restaurant (located mostly in Texas) known by locals for their cheap prices and low quality food.
Texas-based musicians are featured throughout the film including Ruthie Foster, Bob Schneider, Carolyn Wonderland, Adam Carroll, and Ben Burgess.
