I NEVER write reviews, but this one truly deserves it. I just had my daughters 4th birthday there this weekend and I cant say enough good things about my experience here from start to finish. Not only did the kids love it, this was one of the stress-less parties I’ve had.

We all have been talking about how perfect the day was since we left there Saturday. If you’re thinking about having a party here, stop second guessing and just book it!

Coming from an extremely indecisive person 😂 i promise, you will not regret it!
A birthday gem!
We recently celebrated our child's 3rd birthday here and it was a hit with kids and parents alike. Raffaela made everything so easy, that I was able to enjoy the party, too. The children enjoyed the play area and of course, the delicious ice cream!
Attended a children's feeding workshop with pragmatic specialist Lauren Budd. I learned a lot ❤️
