I realize that this is a bit of a long shot, but there used to be a cart on 45th and 5th ave that sold an amazing Lamb Sandwich with green hot sauce. I used to make the trek at least once a week when I lived in NYC. Sadly, I could not find it on my last visit. Anyone know what happened to this cart, and where it may have relocated? Or any other vendor recommendations? I am going to be in Manhattan this weekend and I would love some advice. Thanks.
