IN-N-OUT!!!!! I'd fly out to west coast just to have me a double.
I tried Fat Burger in Vegas... I found myself an In-N-Out the second time I ate another burger in Vegas.
I treated my parents to a seven-course w/wine dinner at a very nice restaurant out in Phoenix...also had In-N-Out during the trip...they liked In-N-Out as much as they did the $$$ dinner. LOL.
