I’m one of the few who isn’t enamored with 5 Guys. I’ve eaten there at least a dozen times, and it’s average to me. I go because others want to eat there, and it’s not bad enough for me to protest. Value proposition is average, but better than fast food.
Their burgers are fresh, which is a major plus. But, I find them to be a bit flavorless and no better than I can do at home, which is the main reason I go to a restaurant.
I do really like their fries, though. My favorite way consume fries is the way they do it...thick cut fried in peanut oil.
Five Guys is OK and will go sometimes. There is one called Smashburger that I like a lot better. I recommend the mushroom and swiss burger.
