While it is not known how often Zaxby's changes its menu or prices, the National Restaurant Association recommends that restaurants review the prices a minimum of twice per year. Some reasons for changing prices or menu items include food cost volatility, competitors' prices and desired margins.
Zaxby's began in 1990 as a local chicken restaurant and chicken is a staple on its menu. Other items can change based on supply of ingredients and demand for the product. If a key ingredient in a Zaxby recipe increases in price, the company may decide to raise the price instead of changing the recipe.
