We have held and attended numerous birthday parties at The Little Gym of Smyrna, most recently for our 6yo son (his request). It gets better every time. The leader was hilarious, keeping the kids moving, laughing and within their comfort zones the whole time. The staff wouldn't let me lift a finger, from serving pizza (we ordered) to cleanup. They even bagged up the birthday gifts and helped us carry them to the car. Best of all, no mess to clean up at home!
