By far my favorite indooor playground in Las Vegas. If you have a toddler under 4 Kinderland is the perfect spot to take them. It's a large enough space that your child can roam and explore, but small enough to keep your eye on them.
The owners are always present and genuinely seem to enjoy the interaction with the kids and I just recently saw they offer a menu and have a delivery that will bring you lunch.
My only complaints is that I didn't find this place sooner!
Also! They do 10 visit stamp cards for 85$ so $8.50 a visit
