The Double Rodeo Burger at Portillo’s is a big, BBQ-style burger with two flame-grilled beef patties, crunchy onion rings, and barbecue sauce that has a kick. This burger comes on a soft, toasted bun and has a smokey, slightly sweet, and delicious flavor. It also has more protein for people who are really hungry. It’s great for those who like a big, crunchy burger with a strong sauce that tastes like the West.
