In reply to dissonance:
Don't bother. The bouldering room has no mats and is tiny.
The walls are mouse-roped and you have to top rope them as there were no wall bolts. After top roping two, I discovered that neither of the anchors were locked off. I reported this and the guy just shrugged his shoulders and said, 'it really isn't that important!' (funnily enough he was running a climbing first aid course in the other room)
The place is filthy and needs a bucket of hot soapy water. I tried brushing some of the crap off but it was thick grease which made everything very slippy.
A guy was telling us that the routes never get re-set and yet they are charging top money to get in this place and they charge on an hourly rate.
