Hello, on one of our days in NYC we are scheduled for Tenement Museum, and then plan to eat lunch at Katz Deli..We have a few hours (3 to 4) afterward and so I wondered about heading over to Brooklyn to eat some ice cream (suggestions on the best?) and to browse a bit and then walk back over the bridge to Manhattan (length 45 minutes?) also the Jacques Torres Chocolates would it be possible to pick some of those up too? Anything else in the DUMBO area we should check out in our limited time there? Thanks!!!!
