Popularized in the 1930s and ‘40s, supper clubs offered Midwesterners social, culinary and cultural stimulation. Tonight from 8 to 10 p.m., Prosperity Social Club celebrates that time-honored American tradition as the Cleveland pub travels back to the days of "classic cocktails and hearty dinner fare" served with flickering candlelight, white tablecloths and lively lounge music. Along with an array of signature cocktails and retro appetizers, Prosperity’s homemade supper club-inspired menu items will include lobster ravioli served in a bourbon cream sauce with arugula and roasted tomatoes, saffron poached salmon served with tomoato cous cous and mirepoix vegetables and choice sirloin encrusted with espresso and brown sugar served with a generous bed of rich, brandy and peppercorn cream sauce, roasted asparagus and a side of caramelized onion mashed potatoes. Reservations for the Supper Club series are strongly encouraged (seatings take place at 7:30, 7:45 and 8 p.m.) but not required. (Niesel)
