I went walking again the other day. From 57th Street (down Broadway) to whatever point I got tired at. I reached my old Madison Square Park rest point and finally got around to checking out the Shack: a food stand in the park notorious as a "must have" destination for hamburgers and ice cream on the foodie boards and for their insanely long lines.
I had a double cheeseburger and a black & white milkshake. Yum, it was tasty. I sat at the tables near the place and actually had a good moment: I was by myself and too bad for that, but things were okay.
