Did this tour a week ago today and it was very nice. Walter was a great guide who took the time to answer questions. The places that we stopped for food were cool too, Eastern European Bakery, BBQ joint, pizza, bagel bite, chocolate and ice cream.
My only complaint were the last two stops. The chocolate factory was a storefront where they made chocolate and our tasting was a piece of candy the size of a dime and while the ice cream at the ice cream place was FABULOUS, it was an ice cream parlor in basically any-town USA, nothing "brooklyn'y or Williamsburg'y" about it. This stop is the end of the tour and you're left on your own to get back, which is absolutely fine, but maybe pick a different area so we could continue to explore on our own. We were left in the section of Williamsburg where there's all chain stores - I suggest leaving us back on Bedford by the mom and pop stores....we would shop if we were left there. didn't need to stop and spend money at Wendys or Duane Reade.
