I think I may get some for tonight. You guys are making me hungry. Their fries are good, too.
Dirty,
I don't think they're owned by the same company. White Castle does'nt franchise and Krystal's does. As far as taste goes, Castle's are better, IMO. I've eaten a lot of both and I prefer Castle's. 4 dbl cheese, 3 singles, fries and shake is hard to beat around 2 am.
