Very knowledgeable guide. Our group was small enough so we could ask questions and dialogue. Our guide talked about the usual things--about history and immigrants and pushcarts--BUT we also visited places that tours usually don't cover, and our guide talked about issues in the 'hood, things tours usually don't bring up, like street art and the Essex Market and current issues.. I loved the graffiti; it's not just scribble. And our guide's restaurant recommendation for lunch in Chinatown was a trip in itself--a combination of dim sum in an old restaurant which must have been a diner and still had the old diner accoutrements with subway tiles on the floor. Lots of small streets. And after the tour, go off on your own (but bring a map.). Walking shoes. Camera, a must.
