Krystal restaurants, both company-owned and franchised, operate in Alabama, Florida, Georgia, Kentucky, Louisiana, Mississippi, South Carolina, and Tennessee. There is a Krystal in West Memphis, Arkansas (directly across the Mississippi River from Memphis, Tennessee), and one in Murphy, North Carolina. Krystal has also operated several restaurants in Texas over the years. It is often compared to the northern restaurant chain White Castle, and other than the South Central Kentucky and Nashville, Tennessee markets, the two restaurants' market areas do not generally overlap.
