Michael Schneider Variety Editor at Large “Grease” fans hungry for a cool slider (a cool, cool, cool, cool slider) or hopelessly devoted to fries will have a chance to indulge via a pop-up version of the film franchise’s Frosty Palace on Thursday, April 6, and Friday, April 7. Paramount+ has partnered with Popsugar to take over Mel’s Drive-In on Sunset Blvd. in West Hollywood for the promotion, timed to the upcoming launch of the new series “Grease: Rise of the Pink Ladies.” It’s unclear whether Danny Zuko’s preferred order (a double Polar Burger with everything and a cherry soda with chocolate ice cream) will be available, but the two-day interactive event will include 1950s-era music and decor, as well as “twists on familiar diner fare” and photo moments. “Grease: Rise of the Pink Ladies” merchandise will also be given away and customized on site.
