Came here with my boyfriend and a couple of our other friends on a Sunday evening - surprisingly they don't close until 9pm usually!
Injanation has a variety of things to do - rock climbing, trampoline park, and a variety of obstacle courses. We stayed for 1 hour (for around $20 each, their rates are a bit cheaper Monday-Thursday though). It was a great way to sneak in some calorie burning, I enjoyed the competitiveness of some of the activities.
If you're looking for something fun and different to do and/or to get the blood pumping you should definitely drop by!
