Good experience with a birthday party here. Staff friendly, helpful, and patiently guided elementary aged kids. KIDS HAD A BLAST, surprisingly?, giggles and grins throughout. Easy reservation, spacious, place cleaner than expected, and above all, simply chill. Kudos to the team. Thank you!

Arisara
We come to Seattle from LA and look for a place for the kids when it rains. We found this place and it’s worth the trip. It was a great experience for the kids, and the staff was very helpful. We will be back if we have a chance.

Heather
My child is autistic and mostly nonverbal, and we stumbled upon this gem of a place today. I can’t thank the staff enough for a truly positive experience. Sensory events are so important for kids, and it was just a wonderful moment as a parent to see an all-inclusive environment, where every child there was able to explore science, laugh, and create something special of their own to take with them. I highly recommend for anyone, with sincere gratitude for to the facilitators.

Roxana
Had the birthday party for 5y, and he and his friends loved it! The staff is very nice and friendly, the slime making process is very fun for kids! Also the party area is great for snacks and celebration. Would have been nice to have a sink with water, but it’s not a deal breaker for us. Had a blast, highly recommend!
