Soft and slightly sweet spongy bun, hot dog, bacon, beans, onions, tomatoes, mayonnaise, cheddar cheese, cotija cheese, salsa verde, mushrooms, guac, jalapeño, various hot sauces.... and if that's not enough there's also mustard and ketchup for the traditionalists. Add great customer service and service from a van, and you have the Nogales Sonoran dog for a mere $3.00! That's a lot of toppings! Good eat, but my only complaint is that the hot dog is not freshly grilled like the vendors on the streets of LA and the bun can get soggy quickly with the topping overload. Very close to the airport and open late, so great for late night travelers like me! The area looks a little scary but these guys get a constant stream of customers so that reduces the scary factor a bit. Accepts credit card.
