We went to Jambo! today for my son's 3rd birthday. The rides were fun, but the service was slow and the package we had purchased was supposed to come with tokens, which were not given to us until we were getting ready to leave. The soft play jungle area was really big and there was a ton of space for kids to run around. The rides went pretty fast, so my son wasn't quite old enough to go on them, so we mostly played arcade games. Food, not so great.... but, it's pizza for kids, and we were there for the amusement, not for a fine dining experience.
I would go again, but only for someone else's birthday party. The cost for the actual party was too high for me to want to book another party there.
