In and out toasts thier buns, which is nice. But the beef in a five guys burger is better.
Both are excellent and fresh cut. Five guys gives more.
Five guys, if that store has them, has an excellent variety of shakes. In and out isn’t bad though.
In and out has excellent apparel you can buy. Five guys has free peanuts.
So food wise, it’s actually quite close with a little personal preference easily giving one the nod over the other, but where they split is this...
In and out you can get a meal for less than the cost of just a five guys burger.
