This review will sound much like my review for Makutus. Jambo is a bit of a different place though. More space dedicated to video games (though many were out of order), the mini golf and Laser tag were a plus and even though it seems they charge you for each go around on those attractions, my son played mini golf 4 times and did the laser tag twice and no one seemed to ask for me to shell out more dough.
The place does need a solid top to bottom bleach bath and dusting. Much of the equipment is worn and as I said many of the arcade games were out of order. There doesn't seem to be any pride in ownership/pride in workmanship in these places. I think the play-places at most McDonald's are better maintained.
The birthday rooms are nice because you get your own space, but they have no ceiling and the building is basically a decorated warehouse, so all the noise from the building comes right in to those spaces. Very hard to hear your own party. At least somewhere like Peter Piper the noise all dissipates in the surrounding area.
Food was reasonably priced though.
Long and short of it. My kid had fun but I wonder if they couldn't draw more business with a cleaner, well maintained facility.
