I recently did the Williamsburg Bites tour with my wife and son (age 21). We all enjoyed the tour. Our guide, Walter, was excellent. He told very interesting stories about the food, the neighborhood and it's history. The food was either excellent (BBQ, pizza and bagels), very good (pirogies) or "what were they thinking?" (the chocolate was awful). Overall, we had a really good time, although I personally did not find Williamsburg the most interesting neighborhood - maybe because I grew up in Queens.
