Concierge.com's insider take:
Down Under the Manhattan Bridge Overpass was a wasteland not long ago. You could practically see tumbleweed bowling down Front Street. Now it's all lofts and home stores and converted factories, but it has a totally different feel from other gentrified Brooklyn 'hoods, since the real estate here is nearly all warehouses. The first section of Brooklyn Bridge Park opened in spring 2010 as a seven-acre expanse at Pier 1 with grass lawns for picnicking and long rows of benches with views of the lower Manhattan skyline and the Statue of Liberty. The ambitious park will eventually occupy 85 acres along the waterfront. Braving the line at Grimaldi's Pizzeria is something of a Brooklyn tradition, and it's certainly worth a stab to sample one of the coal brick-oven fired pies—try the fresh mozzarella, tomato, and basil (19 Old Fulton St.; 718-858-4300). For a pick-me-up afterwards, swing by Jacques Torres on Water Street—its signature hot chocolate, a heady mix of cocoa powder, allspice, cinnamon, and sweet ancho chile peppers, packs a nice punch (66 Water St.; 718-875-9772). Keep walking east on Front and you reach a curious neighborhood called Vinegar Hill, a cluster of small Federal-era brick row houses. If you keep walking east (it gets a bit hard to navigate through the housing projects), you reach the Navy Yard, a massive former U.S. Navy shipyard that now provides work spaces for a burgeoning population of artists and craftspeople and also houses Steiner Studios, a film production complex.
