I've been to two of them. The one closest to the Eastern end of LAX, and the one in Las Vegas on the West side of I-15 across from the Strip. Both times I was told that these were the best burgers on the planet.
My opinion, which is just that, was that they were serviceable, nothing more. Or, to quote Dom DeLuise in "History of the World Part One", Nice. Not thrilling, but nice.
I'm a midwest boy, so it was Bob's Big Boy growing up, and I think there is nothing better than a Romanburger from a Mr. Hero in the Cleveland, Ohio area.
I guess it's where you're from. But I will echo the sentiments of those who are fans of "Fatburger". Those are pretty darn good.

West coast has In-n-Out...East Coast has Five Guys. I always make it point to grab a double double when on the west coast but they don't hold a candle to Five Guys!
I vote a big THUMBS UP for In-N-Out. Every one I've been to have been great for a fast food restaurant. Fast food being the qualification. The one on I-15 is awesome & I go there every chance I get.
I've tried Sonic which was touted as being as good & found the food to be very bad, borderline inedible.

I was so happy when a Tommy's opened in San Diego. There is a place here in Clairmont called EZ-Take Out that has burgers just as good as In-N-Out in my opinion but they have better fries. Burgers are made basically the same. From what I understand the creator of EZ-Take Out was at In-N-Out in the beginning. In-N-Out's fries let me down half the time. Ez-Take Out also has boysenberry shakes, YUM.
The EZ Take Out fries are just crisper, maybe a little thinner. Sometimes In-N-Out just seem wet, like maybe the fresh potatoes are still a little green and not cooking properly.
Went to In-n-out for the first time a few weeks ago, after friends that are big fans recommended it. I tried on severl occasions the hamburger, the double meat hamburger and the proteine style double meat hamburger. Though I found it way better than other fast food chains like McD and BK and the price was quite right, I was a little disappointed, for me the most important thing about a burger is still the meat, anything else can be total crap but the meat has to be perfect, and it wasn't. Don't get me wrong it was OK, and I have to (e.g. when I'm on a freeway) I'd go there again. Anyway I still prefer paying $5 at a non-chain burger joint over a In-n-out burger.
