Ah, 5 Guys - where have you been all my life. I have never paid so much for a burger/fry/drink combo and come away feeling it was worth it. The amount of food you get is ridiculous, the regular fries alone fills nearly 2/3s of a dinner plate.
Add to that the fact the the burgers are juicy, flavourful and allow you to design your own toppings.
Other fast food chains really need to watch out. I have tried them all, even lesser know ones like Fat Burger and In & Out and 5 Guys beats them hands down.
Best chain burger & fries I have found.
