Pizza Hut

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 Roof"s 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 Wing Street, KFC or Taco Bell, and are also found on college campuses, food courts, theme parks, and in stores such as Target.

Traditionally, Pizza Hut has been known for its ambiance as much as pizza. Vintage "Red Roof" locations can be found throughout the United States, and quite a few exist in the UK and Australia. Even so, many such locations offer delivery/carryout service. This building style was common in the 1960s and 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 1980s, the company moved into other successful formats including delivery/carryout and the fast food "Express" model.

The oldest continuously operating Pizza Hut in the world is in Manhattan, Kansas, in a shopping and tavern district known as Aggieville near Kansas State University.
