Remember when Limelight was a Church? Then a nightclub? Then a nightclub for drunk teens? On Friday the transformation will be complete: it will be Manhattan's newest indoor mall, Limelight Marketplace. I don't get it. And I wonder if anyone else will. It seems that Time Warner has almost gotten some sea legs, and it has real stores and restaurants in it. And you can actually find it. Ditto for the shops and market at Grand Central Terminal. This one's a mystery me. Time will tell.
