I live in New Jersey and recently Five Guys started opening franchises here. In my opinion they make the best fast food burger in the area. White Rose is very good as well, but really a different type of burger. Five Guys uses fresh beef, and although well done, the burgers are juicy, fresh, and delicious. The fries are excellent as well, fresh cut and fried twice in peanut oil.
Many people have said that Five Guys is to the East Coast what In-N-Out is to the West Coast. I've never been to an In-N-Out, so I can't make a comparison. I have read a lot of comments on various food forums comparing the 2, and as you can imagine, opinions vary greatly. It seems that slightly more people who've had both prefer In-N-Out though a lot of people prefer Five Guys and say there is no comparison. Jason Perlow of Off The Broiler, whose opinions I respect, prefers Five Guys.
Those of you who have been to both places, which do you like better?
