I went here with some friends for a group outing, overall it was a cool experience.
The bar/waiting area is really interesting with motifs such as ski lift benches, etc.
If ambience is important to you, this is something you will appreciate.
The Chill Room experience was cool, it's a great opportunity for some cool selfies and photo ops before you start to get cold :)
In terms of activities, there is not a lot to do. There is bar (drinks were so-so), and some ice games. There could be more work put into developing these a bit further.
Overall I say this is a great spot if you're looking to cool off in the summer, definitely a "go once" type of experience in my opinion though.
