The most unique and fun wedding venue! (Ceremony in the planetarium, come on!)

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!

Bride here, I could not have asked for a more perfect wedding. Everything from beginning to end was beautiful. Lauren and her staff made sure everything was taken care of and the food was delicious. The level of professionalism was amazing and I could not have asked for a better experience. My guests were amazed by the Planetarium and the City View space. Even our officiant brought his office friends to see everything. Lauren was so patient with me and my 1,001 questions. I wish I could do more besides review them here, I've been going to COSI since I was a little girl, my very best memories are of the Planetarium. I never thought I'd get married in it. Make no mistake, this is a beautiful place for any bride and groom to say their vows. Some reviews are upset that the museum caters to children (a clear indication if you glance at the website), but there are adult exhibits as well and all of my guests had a blast! We will continue to visit COSI, and can't wait to see what they have in store for the future!
