It ain't In & Out( a California original) and that's okay. I like White Castle burgers. Small and tasty and more like slider burgers. it's great that they have a presence in Vegas and right on Fremont street. Not only did I eat a few classic White Castle beef burgers and fries but had the spontaneous gratuity of sampling the chicken burgers. A fellow patron at White Castle ordered with eyes bigger than their stomach and couldn't finish their chicken burgers which they offered to me. Not one to turn down great tasting burgers and I humbly accepted their offerings and morphed my original order into a smorgasbord of beef and chicken burgers.
In a word: TASTY. Tasty and satisfied. Prices are okay, ambience good, orders filled quickly and open all night ! And located in the thick of the Fremont Street Experience !
