I feel like I'm cheating on In-and-Out whenever I eat at Five Guys. I'm going to be honest. I LOVE In-and-Out, the pride and joy of the west coast.
BUT Five guys is pretty darn good. I love that you can customize your burgers. Gooey cheese... grilled onions, mushrooms, peppers what ever pleases your taste buds.
The fries were excellent and even better than In-and-Out, especially when you add their Cajun seasoning. The prices were decent (though more expensive than In-and-Out after you include their fries and drink).
Is this the best fast food burger I've ever eaten? No, but it is pretty gosh darn good for fast food burgers. This is better than your average burger, so look out Culver's. I'm hungry now!
