It's funny....people always tell me I only like In-N-Out so much because I'm from California. Well, true, I am (originally), but I am from Northern California, and I left before they even starting expanding to Northern California.
@Littlegoo :
I understand what you're saying and the comments you must endure in regards to your California roots on several fronts. However last I checked California is still part of the United States. So if you think In-N-Out burger is one of, or the best you've had that's okay. We all tend to gravitate to the familiar. Especially in regards to our taste in food.
That said in my opinion the cheese burgers at Pappas BBQ tops them all. But that's just me.
