Just had my son's 3rd birthday party here. Everyone had a great time!! I originally wasn't too keen on the idea of not being able to bring in my own water bottles or cups, but I understand the legality of their reasoning and everything worked out just fine anyway. (It only takes one irresponsible moron to ruin it for everyone else!) The staff was friendly and helpful. The owner checked in on us to make sure everything was good and our party attendant was on point! HIGHLY RECOMMEND CHELSEA!! The private party room with its own bounce house and slide was a huge hit and so amazing for the party guests to have fun without worrying about the big kids taking over, especially since the majority of our guests were 2-4 yrs old. But they were also able to go out with the masses and play with everything too. This place is huge (and clean) and it was nice to have a large space for the birthday party without feeling crammed into a small room. We will be going back for sure!
