My daughters wedding reception was outside COSI on the English Plaza with the cocktail hour in one of the courtyards. From a mother-of-the-bride point of view.....The day of the event was great!

The COSI event staff went over and above. They were attentive, ready to help, all while staying late making sure everything went well. As a first time mother-of-the bride I didn't know what to expect. We had trouble getting on the same page early in the process. We struggled in understanding what was included and what was not. Communication could have been better. The issues along the way caused us to be skeptical that all was going to go well. With the help of our wedding planner (Ashley Stephan) and the COSI event staff (Lauren, Savanah, Aaron and Kayla), the English Plaza was an awesome place for a wedding reception.

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!

I'm the bride's brother. I was not involved in the planning. My sister was looking for a 'sophisticated venue with good food and good views." It was priced a little more than a hotel wedding....

Disappointed experience

Reviewed on 8/27/2012 Jessica L

I was disappointed with COSI. I was double-booked with Festival Latino which wasn't recognized as an issue until the City of Columbus didn't let me get the park permit. COSI claimed they didn't know the fesitval used their plaza which I find hard to believe when it's been... Read More taking place for years. Plus, there are tons of pictures on the festival's site AND you have to pay to rent the space. They moved us inside and gave us a discount as a result, but we ultimately booked there because of the plaza. We would've gone elsewhere had we known we wouldn't be on the plaza for the reception. A big scene was made the day of the wedding that my coordinator had 5 interns to help. After the ceremony, there was no one to direct guests to the cocktail hour in the Progress Exhibit. My event coordinator left around 9-930pm and passed the reception on to the catering manager who was nowhere to be found. I had to ask a catering staff member (who doesn't work at COSI) about turning down lights and she had to use the walkie at the front desk to try to reach him (15 mins later he shows up). Our families provided a lot for the wedding. My aunt made our cake and COSI tried to keep her tier supports. We left to do a sparkler send-off, and when our families came back, the room was almost broken down completely (which is fine, I understand). The issue was anything other than cameras, jackets, cell phones or purses were pitched. We had a photobooth and all our family/wedding party lost their pictures because the staff pitched them. My sister got into a disagreement with a staff member because COSI said the vases I brought into the facility belonged to them - wrong. Our wedding cake was a wedding present from an aunt, and COSI just threw it out without asking us about it. My sister was able to stop them from pitching our dessert table which, again, many family members spent time making (2000+ cookies) as a gift to us and our guests. Lastly, we were charged for 60 cars which was supposed to be an estimate while the actual was provided at the end of the event. No one was in the booth at the end of the night to calculate that so we were charged the full 60 cars. Our hotel was the Double Tree across the river, and a lot of our guests checked-in before the wedding and walked over knowing they would be drinking. COSI was helpful getting me a green room at Noon the day of since the hotel wouldn't guarantee check-in. I liked my new event coordinator a lot more than the previous lady (who resigned for another position), but I was really surprised no one was around during the reception.

The only hiccups we had were that when people were parking, the attendant didn't ask if they were with the wedding so many of our guests had to pay for parking, and the other slight issue was that the bar at the cocktail hour was not done being set up when people got there yet the bar at the reception was set up by 4:30 (reception started at 7) and they wanted to charge us for an extra 1/2 hour of the bar being open. Still working out the solution to that, but if that's the worst that happens, in the grand scheme of things, no big deal.

We had booked COSI based on reviews and our initial meeting, with high hopes and expectations. However, shortly after, our COSI event planner changed from Samantha to Anna. That is when problems, frustration, inconvenience, and stress occurred on a consistent basis. It was... Read More deeply saddening to see my wife and our parents upset and worried about our big day. Event planning is part of my wife's job duties, and she repeatedly stated how unprofessional incompetent Anna was. Objectively, our overall event planner and others remarked at the incompetence. An example, my wife sent an email, to which Anna responded that she could not respond because she had to run off to a happy hour. Not only was Anna not there on the wedding night, but my in-laws themselves had to tell the staff that the Dipping Dots cart we rented need a server. We were told that the outside courtyard for our ceremony would be cleaned up, it was was not done. We had paid extra for beer to be poured into glasses, it was not done. We were told we would be provided extra rooms for babysitting, vendors to change in, and for us to use to get ready, they were not provided. To be fair, the other staff at COSI were great and we were actually somewhat thankful Anna was not there that day. Thankfully, like most weddings were things go wrong, most guests were none the wiser to all the incompetence we experienced (except the unclean courtyard and beer not in glasses). Overall, we were very disappointed in COSI's customer service. Thankfully, our caterer (Cameron Mitchell) did an outstanding job and really made our night special.

While COSI is a beautiful unique place to get married...keep in mind that their primary business is that of a science museum. And they make that clear on your day. They are completely disorganized, rude, unreliable and completely overpriced. My wedding planner assured me that... Read More we could take pictures anywhere in the museum..and when my photographer cost $5,000 I thought well that is GREAT! Well my post ceremony photos happened to start at 5:30 and with the family photos taking 15 minutes we were excited to start the fun photos in the exhibits that we had "full" reign of! Security ushered us out after 15 minutes because the exhibits were closing. WOW! After I paid COSI a ton they couldn't chill out for 15 MORE minutes? Even my photographers were annoyed with how rude the staff AS WELL AS MY WEDDING PLANNER WAS. She didn't show up for the rehearsal...which she promised she would be at. She was no where to be found before my wedding, so my family set up the chairs for the ceremony and then she claimed her staff was on their way to do it....but with 30 of my family looking for someone you would have thought they could have found at least one staff member...hmm let's see...the female bar tender rolled her eyes at 8 of my guests, poured glasses of wine 1/4 full, muttered things under her breathe when someone would order a drink she didn't know how to make...however when she rolled her eyes at the Father of the Groom (who is paying her to do her job) the Bartenders manager had her go home and rectified the situation. SO thank you to her. My reception was outside and it went into the night...i asked a couple of weeks prior to my wedding if we needed to invest in some lighting for the Plaza wedding planner said they have never had a problem and that the skyline and the COSI lights were more than when it got dark and my votive candles on the tables were light it was black as..well NIGHT. Now my photographer and videographer have no light and couldn't do anything the rest of the night...Just another thing that could have been avoided if she would have done her job...but she left a half hour after the ceremony so eh what does she care. I know this sounds like I'm a psycho bride that wants everything her way...but I'm not. My wedding was PERFECT! However it was all due to my family and friends stepping up...we would not have had music if it weren't for friends testing the sound system 2 hours before the ceremony..finding it didn't work and then bringing in there own amps and sound system. MY GUESTS did THEIR job and because of them it was perfect! COSI is beautiful there's no doubt about it, but then again so is a lot of places for the same amount of money or less.
