After nearly a year without roller-skating, the pastime returned to Coney Island with the opening of the Lola Staar Dreamland Roller Rink yesterday. The star-studded event - Marissa Tomei, Ashanti, and of course Lola Staar (aka Dianna Carlin) were there - looked like a grand ole time. The portable roller-rink is located in the Childs Restaurant Building at 21st St. and the Boardwalk, where Carlin believes she can reach an agreement to use the building until a permanent tenant is found.
