Besides In & Out (which are VERY yummy), another So Cal chain not to be missed is Fatburger. It makes me hungry just thinking about it!! They are de-lic-ious!! If you are going to spend a day at Knott's, I would highly recommend trying out this restaurant. (There's one about a block from Knott's, in between Knott's & the Buena Park Mall). Mmmm...I think I might just have to go there for lunch today.
