A pancake house, pancake and waffle house or waffle house is a restaurant that specializes in breakfast items such as pancakes, waffles, and omelettes, among other items. Many small, independent pancake houses, as well as large corporations and franchises, use the terminology in their establishment names, most notably the International House of Pancakes (IHOP), Waffle House and The Original Pancake House. Most pancake houses are dine-in, although most will offer carry-out as well. Many are open until around 3 a.m. Exceptions to this are large chains such as IHOP and Denny's, which are usually open 24 hours. Some independent pancake houses are found in strip malls, or exist as stand-alone structures that have been re-fitted, such as a closed-down diner or retail store.
