Kids Castle in Newark is a great place these days for kids birthday parties. The owners have given it a face lift recently. The various play things have been fixed and re-organized. There is now a giant screen on which they can play movies, TV etc.
Desi pizzas are an added attraction (this has been available for a while). Pav Bhaji pizza being my personal favorite. Beer is a recent addition too. Nice way to spend an evening with friends and family. Kids are sure to have a great time.
They also have a website (who doesn’t) these days. Though a crummy site, it gives you a starting point.
