In-and-Out Burger vs. Fatburger

It's is our last day in LA and although the trip has been packed with fun, there is still one big descision to be made.  Should we eat In-and-Out Burger or should we have a Fatburger?  This predicament presented itself when we saw a Fatburger on the side of the road.  All along we had planned on eating In-and-Out burger, but what we had not factored in was the aroma and allure of the shiney happy Fatburger that caught our eye. Hmmm. What to do?  We could let gluttoney take it's course and go for both.  I don't have the stomach for it, but I know E does.  Whatever the choice, I am optomistic for a good outcome.
