I've heard that this place and In n Out Burger are the new kings of American fast food. I really liked In n Out when I've visited California/Nevada and I was really looking forward to the east coast equivalent. I have to say the burgers are really good, maybe better than In and Out and definitely better than McD, Wendy's, BK, etc.
I didn't however like the fries. I had the cajun fries and my girlfriend and other friend had the regular fries. I enjoyed the cajun seasoning but the fries were overcooked and not very tasty. yes they were all over the bag (like some other reviewers mentioned) but that was on purpose. After they put the fries in the bag they dump a bunch more in with them so I can't really complain about that.
If you in the area I'd definitely try them out. I live over half and hour away and I consider my trip worthwhile.
