I think Five Guys burgers are better than most, but not great. OTOH, they have the best fries in the business. Sometimes I'll order a large batch of fries, and reheat them in the air fryer. The way they load you up, I can usually get 3 or 4 servings out of it.

And Five Guys prices are immoral. The last time I got a double bacon cheeseburger, small fries and a drink, and it was $25! That was the end for me.

And I've never been impressed by Shake Shake. They seem to be comparable to Burger Fi, which I never see mentioned anywhere. Good, but not great, and definitely not worth the super premium price.
