Great thing about mom and pop shops, they offer some of the best food. Chuck Box did not disappoint. Made a visit when I was in Arizona. It's like a Subway, you walk in, you pick the meat then the toppings then pay.
Meat was super moist and super delicious. Only downside to this place aside from the "CASH ONLY" is the crowd. Since it's located really close to ASU, expect no seats.
