Here's the edited review: There are many fun and challenging walls to boulder here! It's rather crowded on weekends, especially after lunch. Service from the staff varies from person to person and wasn't as expected, contrary to other Local Guides' reviews. There's a neat training wall on the second floor to improve one's technique instead of hogging the walls downstairs. I think they change the routes rather frequently, as we saw new ones when we were leaving.
