We had a birthday party here for our 7 year old son. We live in the suburbs, so I wasnt sure how many kids would make the trek to the city and EVERYONE RSVPd b/c they were so excited. I cant reccomend this place enough! they were SO responsive to all my questions and concerns beforehand, EXTREMELY accomodating when we had people rsvp at the last minute and very friendly and inviting. And they set up an awesome party that the kids really enjoyed. we had so many kids (and mostly boys) so our party was chaotic, and they never once showed signs of stress or uneasiness. They were so calm and friendly to the kids and the kids had a wonderful time learning! I definitely reccommend this place as an alternative to the bounce house party!
