They are different, but the same ~ all the best. Can't get better.
My favorite IN and OUT is right there with Vista and Oceanside meet. My favorite 5 GUYS is one of the originals just down the street.
The fries are different though. IN and OUT fixes a broad cross section version of the McDonald's stuff. 5 GUYS makes these traditional size fresh oil fried versions.
Plus 5 GUYS has always served mushrooms.
It's good that IN and OUT is now 2.5 hours closer!
I tried 2 different 5 Guys and I thought it was of average taste and way too expensive.
On the scale, In-N-Out is a 10, Whattaburger is a 7, 5 Guys is a 5. Oh, Tommy’s (also a So. Cal. icon) is a 8.5. Carl’s/Hardees is a 6.5
