To call Five Guys the east coast version of In-N-Out does a great disservice to them and their burgers. Yes they both hand cut their fries in the store, but where In-N-Out uses vegetable oil Five Guys uses peanut oil and offers Yummy Cajun Fries.
Their burgers are also freshly made in the store. The best part though is that there is no stupid secret menu that you need to memorize in order to get the burger exactly how you want it. Five Guys has it all spelled out for you and a wide selection of toppings and condiments to choose from.
