It’s true. White Castle started in the ‘20s and that’s what he did for that very reason.
Have zero idea what Krystal is.
Krystal is only in the southeastern US and very similar to White Castle. Really big in Tennessee and Georgia. White Castle can be found in 11 Midwestern and Northern states. Krystal in 12 throughout the South. Even though they’re separate companies they show little signs of try to expand into each others territory. Only places they compete head to head are a few cities in KY, and Tenn.
