Pizza Hut is split into several different restaurant formats; the original family-style dine-in locations; store front delivery and carry-out locations; and hybrid locations that offer carry-out, delivery, and dine-in options. Many full-size Pizza Hut locations offer lunch buffet, with "all-you-can-eat" pizza, salad, bread sticks, and a special pasta. Additionally, Pizza Hut also has a number of other business concepts that are different from the store type; Pizza Hut "Bistro" locations are "Red Roofs" which offer an expanded menu and slightly more upscale options. "Pizza Hut Express" and "The Hut" locations are fast food restaurants. They offer a limited menu with many products not found at traditional Pizza Huts. These type of stores are often paired in a colocated location with a sibling brand such as WingStreet, KFC or Taco Bell, and are also found on college campuses, food courts, theme parks, and in stores such as Target and Walmart. Vintage "Red Roof" locations can be found throughout the United States, and quite a few exist in the UK and Australia, and México. Even so, many such locations offer delivery/carryout service. This building style was common in the late 1960s and early 1970s. The name "Red Roof" is somewhat anachronistic now, since many locations have brown roofs. Dozens of "Red Roofs" have closed or been relocated/rebuilt. Many "Red Roof" branches have beer if not a full bar, music from a jukebox, and sometimes an arcade. In the mid 1980s, the company moved into other successful formats including delivery/carryout and the fast food "Express" model.
In North America, Pizza Hut sells "Stuffed crust " pizza, with the outermost edge wrapped around a cylinder of mozzarella cheese; "Hand-Tossed," more like traditional pizzeria crusts; "Thin 'N Crispy", a thin, crisp dough which was Pizza Hut's original style; "Dippin' Strips pizza", a pizza cut into small strips that can be dipped into a number of sauces; and "The Edge pizza," where the toppings nearly reach to the edge of the pizza. There was also formerly a crust that was not as thick as Pizza Hut's pan pizza, and not as thin as its thin crust. This crust was used on the Full House XL pizza and discontinued in 2007. There are regional differences in the products and bases sold.
