There are three Arbynator sandwiches to choose from small to big depending on how big your appetite for roast beef is: the Classic Arbynator, the Double Arbynator, and the Half Pound Arbynator.

They pretty much took every existing thing in the kitchen and put it on one sandwich for you in a delicious way.  The Arbynator features roast beef, cheddar cheese sauce, Horsey Sauce, bbq sauce, and Curly Fries in between a sesame seed bun.
