The most unique and fun wedding venue!

We had our entire wedding at COSI, and we couldn't have been happier with it! We knew we had a unique venue, but our guests have been raving over what a cool experience it was. Savannah was the most amazing coordinator, and she worked so hard throughout our planning process and on the day of to make our day perfect. Caitlin in the planetarium did an amazing job building us a custom show for our ceremony. The entire staff was so kind - even our guests were commenting on what a wonderful team it was. Thank you, COSI, for helping us have the perfect - and coolest - wedding experience!
