People go nuts about this spot, so I had to try it during a short trip to NYC.
You're about as likely to win the lottery as you are to find a seat here. The line was out the door, even at 2pm on a weekday, so I took my falafel to go. Once I got my order, it took all my willpower not to devour it as I walked out the door. My restraint lasted just long enough for me to reach Jackson Square, where I sat on a ledge and munched happily on my prize.
In spite of all the hype, I was not disappointed. Their falafel really is phenomenal.
