At first we were a bit reluctant to take the tour, as it seemed to only cover East Side, and not "everything" like some other NYC food tours claimed they did.
However we're very glad that we went in the end!
Liz was very nice and she explained a lot about history of different neighborhoods and places. We went to many different stops and they were all special, including Malasia jerky, soda shop, Pickle Guys, Essex street market, Kosshers bagels & bialys and some special bakeries and of course Kat'z deli.
All in all a very thorough experience and we'd recommend it to anyone.
