I first tried the Five Guys that opened near my office in Hackensack, NJ
We ordered lunch to go, and like you I was less than impressed... it wasn't bad, but there was NO wow factor either... it was just plain old fast food.
Now the last time I had Five Guys at the Washington Dulles airport on my way back from Detroit (with only 50 minutes between flights, lol) the burger, even with the squished bun... tasted absolutely delishious. I ordered the bacon burger with shrooms and bbq sauce an dit was great! But it was completely different from my last In-N-Out experience which I'll repeat this November.
So to answer your question... YES! I'm down for a Hoboken or NYC Five Guys DO... but its more for the sake of meeting new people from FT than for the food, heh
