If you're in NYC, definitely stop by one of the Shake Shack venues; there are lots of locations, so maybe you'll even accidentally stumble across one like we did! Here's a copy of the full menu to help keep your salivary glands in shape: http://www.shakeshack.com/location/upper-west-side/
The address for this location is: 366 Columbus Ave. (between 77th & 78th) New York, NY. 10024
I've also been to the original location in Madison Square Park, which is outdoors and has plenty of seating.
