Double Seven, which lost its West 14th Street space in 2008, is almost ready for business again. At a dinner sponsored by charity God’s Love We Deliver at the Empire Hotel, owner David Rabin was overhead telling “Top Chef” star Gail Simmons and supermodel Doutzen Kroes that the club will finally reopen this summer in a new location on Gansevoort Street. Kroes was also heard telling Simmons that the next season of “Top Chef” should be held in New Orleans — her favorite food city in the country.
