WHAT PEOPLE SAY ABOUT NINJA REPUBLIC
DOREEN T.
The owner, Regan obviously cares about safety, cleanliness, and encouraging kids to push so they can get better (at an appropriate level). He knows all the regulars.
We love Ninja Republic :)
JONATHAN D.
Great course for kids and adults. I was expecting it to be basically a kids place (and it was great for that especially since for parties you rent out the whole space) but there are tons of great obstacles that will challenge almost any adult.
LILIANA M.
If I can give 10 stars. I would. The owner is amazing, and he definitely knows how to take care of his customers. He really is involved and interested in just challenging the kids and understandingwhat their doing. This place was amazing.
