If we're being specific, it is two flame-grilled beef patties side-by-side (alas, no extra long beef patty), topped with American cheese, onion rings, and barbecue sauce on a toasted long sesame bun.
I'd be remiss if I didn't point out that, at that price point, buying two Rodeo Burgers (at $1 a piece) and adding a slice of cheese to each (a 50 cent upcharge although it may vary) would cost $3. So it'd only be cheaper if you bought two for $5.
While the Extra Long BBQ Cheeseburger is new here, it's something that's been offered before over in a few countries in Europe, but with three patties instead of two, which pretty much means our version would simply be the "Long BBQ Cheeseburger" over there.
