Pump It Up, is a relatively new children's entertainment place in Kirkland. It seems to be quite popular with the younger crowd these days for birthday parties, ever since Rainbow Playsystems shut down their party warehouse. Smaller kids really seem to love it here. They get a lot of energy out. Bigger kids like it for a while, but get bored with it pretty quickly. If you've got young ones, though, its great to have another indoor party option--away from home!
