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 ❤️
Celebrated my youngest 8th birthday yesterday and we’re are ABSOLUTELY PLEASED with the service provided! The kids had an amazing time during free play, doing a fun craft and enjoying their delicious ice cream. Spacious enough for the parents to be comfortable while waiting for kiddos enjoying coffee and treats. Highly recommend!!
