A few weeks back, I went on a self-guided noshing walk around the Lower East Side and Chinatown; I highly recommend it as a way to spend a sunny Sunday. I followed it up with a ridiculously long walk -- hope that helped to counterbalance the caloric intake.
Heebster at Russ & Daughters (I only ate half)
Full sour pickle at The Pickle Guys
Jam filled square doughnut at Doughnut Plant
Optional stop at Kossar's Bialys (for breakfast later in the week)
Wave hello to Mark at Pizza a Casa
Spicy pork jerky from Malaysian Beef Jerky
If you can handle more, there are other good stops, but I was definitely done by then (I didn't even get any jerky, actually). Eat and enjoy!
