COSI After Dark: a 21+ Event! It's COSI without kids!

Grab your friends and start your weekend early with COSI After Dark, an evening event series exclusively for adults ages 21+. Each month showcases a different theme - from Wizard School to Dinosaurs - and each features activities, games, and experiences you can't get at any other visit to COSI. Explore the building, ride the High Wire Unicycle, and best of all, experience COSI without kids, all while enjoying craft beer and themed cocktails.



Admission:

Member - $14
Groups (12 or more) - $16
Nonmember (in advance) - $20
Nonmember (at the door) - $25
