In the city of Tucson, AZ where it is sunny 350 days of the year and there is a culinary fusion of Tex-Mex and California Cuisine Casey faces his next challenge. Along the way he stops off at Boca Tacos y Tequila to try their Sonoran Taco Dog. At Baja Cafe, Casey goes to check out their Tucson-sized breakfast options including their Wyatt Earp Benedict. Being the first to take on Pinnacle Peak's Rib-diculous Challenge, Casey will need to eat 2 racks of ribs in one hour.
