"We had such a fun day here..."
We had such a fun day here with the kids. They loved all the interactive stuff—actually, I should say they were completely hooked on it. It was really nice seeing them stay engaged and excited the whole time.

"Felt secure booking through them"
Used cosi.org to check tickets and plan our visit. The site felt safe, pages loaded fine, and nothing seemed off with payment or info forms. Emails looked legit too. Knocked off one star since a few pages were annoying to find, but security-wise, I felt good.

"Booked fine, just slow"
Got my tickets booked, but the site was kinda slow and the confirmation took a bit. It worked in the end, just not super smooth

"Good food options inside"
I had a good feeling when I saw the food choices inside, it turned out fine. There were some decent options to pick from. It did feel a little pricey for what it was, but my gut said it would do the job, and it did.

"I went to cosi mostly to check out..."
I went to cosi mostly to check out the special exhibit, and it was decent overall. There were definitely some fun parts and a few hands-on things that were cool, but it also got annoying because certain areas were crowded and some of the stations either weren’t working or didn’t work that well.
I’m glad I went, but I wouldn’t say it totally lived up to the hype. Kids would probably still have a good time, and there’s enough there to make it worth a visit, but I’d check what the exhibit actually includes before making a big deal out of going.

"Fair prices for a full day out"
I felt like the ticket prices for COSI were reasonable, especially once we got inside and saw how much there was to do. I’m usually quick to notice when a place feels overpriced, but this didn’t come across that way to me.

We ended up spending a big part of the day there, and it never felt like we were rushing around just to justify the cost. The kids had plenty to keep them busy, which makes a big difference when you’re paying for a family outing.

Getting tickets online was simple, too. It’s not the cheapest activity around, so I wouldn’t say it’s a bargain exactly, but for the amount of time we spent there and what was included, I’d say the pricing felt fair.

"Absolutely the Best Fun for the Kids"
The programs were super hands-on, and I’m completely convinced my kids could’ve stayed there all day without getting bored. They were busy the entire afternoon, having fun and actually staying engaged, which is basically a miracle

"I was impressed with how well the place..."
I was impressed with how well the place was taken care of. The floors looked freshly cleaned, the common areas were tidy, and everything felt maintained instead of worn down. It made the whole experience feel comfortable and easy.

"Fun for the whole family"
I went with my 5-year-old and 12-year-old, i was pleasantly surprised that both of them found plenty to do. The adults had a good time too, so it didn’t feel like one of those places that’s only geared toward little kids. Small win for me: nobody complained about being bored the whole time!

"I went with my kids and was..."
I went with my kids and was impressed with how clean the place was overall, especially the bathrooms, which isn’t always the case when you’re out with family. It made the visit feel a lot more relaxed and comfortable. Nothing overly fancy, but it was well kept and easy to enjoy our time there.

"Way less crowded than other places, great visit"
We went to COSI on a weekend and I expected it to be packed, but it really wasn’t bad at all. Compared to other museums and kid-friendly places we’ve been to, it felt much easier to move around and actually enjoy everything. There were a few spots where kids had to wait, but the lines moved quickly. It made the whole day feel more relaxed and fun instead of stressful...

"I can see why people seem to..."
I can see why people seem to like this little shop. It had a bunch of cool science-themed stuff, and I ended up finding gifts for pretty much everyone. Definitely the kind of place I’d tell a friend to check out.

"Worth it for a full day out"
We had a really good time at COSI and felt like it was worth the money. There was plenty to see and do, and the kids stayed busy pretty much the whole time, so we never felt like we had to rush through anything. The food was a little on the expensive side, but I guess that’s kind of expected at places like this. Overall, it was a fun day and felt like a good value, especially if you’re planning to spend several hours there.

"Long waits, but the kids still had a good time"
The lines were annoying, and there were a few moments where I was just standing there wondering why we didn’t bring more snacks or maybe pick a less busy day. But overall, the kids had a lot of fun, and I guess that’s the main thing. By the end, they were still smiling and talking about their favorite parts, so despite the waiting around, it turned out to be a good day

"We had a really nice time at..."
We had a really nice time at COSI. There are tons of hands-on science activities, and my kids were having so much fun they didn’t even realize how much they were learning. A few areas did get crowded, so I’d suggest going earlier in the day if you can. Overall, it’s a great place for families looking for something educational but still fun for the kids.

"Kids Had Such a Fun Day"
I took my kids here and they had a blast. They were busy for hours with all the hands-on activities and different fun areas to explore. From my experience, it’s a great spot if you want something that keeps kids entertained and engaged. It did get a little crowded, but overall we had a really good day out

"The membership has already been worth it"
We got a COSI membership this year and, it’s already paid off. We’ve taken the kids a few times now, and it’s so much nicer not having to think about buying tickets every single visit. We can just pop in for the afternoon and not feel like we have to do everything. There’s always plenty to keep them busy, which is great, especially on rainy days or when they’re off school.
