I just had my wedding catered by The Barn Restaurant in Tustin, CA. Talk about excellent! The Barn is an actual old-style two-story barn converted into a restaurant. The interior has a number of farm implements and other memoribillia from the midwest. They specialize in wedding banquets, but also serve fine food every day of the week. They have some of the finest prime rib you can sink your teeth into. Service is pretty good too!
