Kids N Action
Indoor play space with a soft play/ball pit area for the youngest kids, a larger softplay area with some fun gym activities (like a rope swing) for bigger kids, plus a couple of indoor rides and arcade games. It's safe and fairly clean, though noisy. Just know that it is a Kosher place so it is a) not open Friday afternoon or Saturday during the day and b) you can't bring in any food. They do parties with kosher food.
Soft Play: Tunnels, Mazes, Slides, Ball Bath, etc.
Birthday party venuesKids N Action! Cheaper and way more fun than many other options. We did our 3yo birthday there, all kids of all ages had a blast. It’s like an older school chuckee cheese plus a couple rides. It’s in Midwood I think that’s the only downside but right on the F train I think.
