Marco’s Restaurant in Lewiston will host an evening of improvisational comedy with Mainely Improv on Friday, Sept. 21. “We make up comic situations based entirely on suggestions from the audience. Every show is unpredictable and has a life of its own,” said Dan Marois, owner and producer of Mainely Improv and Mystery for Hire. “Our challenge is to take an audience suggestion, no matter how bizarre it may be, and portray a scene — immediately,” he said. Doors open at 7:30 p.m. with the show at 8 p.m. Tickets are $12 per person, which includes the show, cabaret seating and a cash bar. For reservations, call 783-0336. For more information, visit www.mysteryforhire.com.
