Who knew that Guy Fieri was such a Broadway enthusiast? Turns out that the host of Guy's Grocery Games ( Sundays 8pm/7c) is a theatergoer after all, and on Saturday he celebrated his love of the live stage by hosting a party inspired by one of his favorite shows, Rock of Ages, during the New York City Wine & Food Festival.

Standing tall atop the second-floor bar at his restaurant, Guy's American Kitchen & Bar, Guy told the packed crowd that he and his family have seen the musical and enjoy its '80-style jams, so it was only fitting for him to invite the cast to belt out some of their signature tunes right then and there, as the show's theater is located just steps away from his Times Square eatery. It didn't take long for the scene soon to turn into a dance party when Guy manned the microphone on stage and added his own rock-and-roll twist to the cast's performance.

In addition to the impromptu concert, guests enjoyed some of Guy's restaurant's best cocktails and munched on such comforting favorites as Bacon + Chicken Mac 'n Cheese and Sashimi Tacos topped with wasabi, plus passed sweet treats, like mini profiteroles and individual strawberry cheesecakes. Fans were treated to an extra-special surprise when two more Food Network stars, Guy's friends Robert Irvine and Iron Chef Masaharu Morimoto, stopped by to join in on the action. The three danced behind the bar while mingling with guests, passing out drinks and toasting to the event with the crowd.
