I was pretty nervous about coming here with my slight fear of heights and all but I actually thoroughly enjoyed my time here! They have a free orientation for beginners which includes a tour of the facilities and basic instructions on how to fall properly to avoid injury.
I spent the day getting the hang of bouldering, which I think means rock climbing without ropes/harnesses. There are different levels of difficulty for bouldering, indicated by the different colours of rocks. I only got up to V1 but even those were tricky - you have to think strategically about foot/hand placement and the order of your movements.
I can see this being a great place for birthday parties or small groups of friends to just hang.
