While this slice shop caters to the pizza-loving crowd, it also serves a mean cheeseburger, beloved by regulars for its girth and bubbling cheese. Its pizzas are whoppers as well. The specialties, like Jackpot (pepperoni, sausage, ham, ground beef, onions, mushrooms, green peppers, green and black olives and extra cheese), come large and in charge, preparing you for a food coma. Naturally, build-your-own pizzas are available. Among the options is a sauce choice, which includes traditional marinara and KC Masterpiece brand barbecue sauce. Unlike other chains, Blackjack gambles beyond putting burgers on the menu. One of the pizza toppings is anchovies. The high sugar-octane sweet tea and onion rings are also magnets to this outpost of a Colorado-based franchise chain founded by Vince Schmuhl in 1983.
