Organizer: Nerds at Heart

What to expect: As with the other Nerds at Heart events, this fest at the Holiday Club allows you to show off your prowess at trivia quizzes and board games. You'll get the chance to win some especially nerdy prizes and, if you're lucky, you might find a date for Valentine's Day! Admission price includes one cocktail, entertainment by special guest performers, and chances to win nerdy prizes, including tickets to Drury Lane Oakbrook's "Funny Girl."

Tuesday's event is gay-centric, and includes dating-themed mini-performances from local singer Amy Armstrong and Ms. Bertha Mason (actor/chef Michael Bowen) of "Baking with Bertha." On Wednesday (hetero night), you'll enjoy interactive comedy from Wishbone Theatre Collective, cheesy karaoke and the chance to win a date including tickets to Landmark Century Centre Cinema and a Noble Tree Coffee & Tea gift certificate.
