This is one of those unique famous places that any food nut wants to try once in their life. I went there on my first visit to Arizona last year, and it pretty much was what I expected based off of tv specials and internet videos and interviews. You get a decent burger at a decent price, and then you go up to the fry-bar and grab some fries and add some toppings to your burger.
There's something rewarding about going into a place that says it will kill you, and walking out alive afterwards. The experience comes complete with having to wear a hospital gown, and being waited on by "nurses". The angled mirrors on the inside of the serving area are a nice touch ; )
Now that I moved to Arizona, I'm sure I'll be back each and every time a new friend or family member comes to town to visit me.
