It's been awhile since summer 2006, which is when Laurence Cresci shut the doors of his Manhattan Grille in east Midtown. But that doesn't mean the restaurateur behind Portofino Grille is done with the space. He's planning to open Creston's Bar & Grill, a steakhouse with American favorites, there in May (319 E. 53rd; 212-888-6556).
