Yeah, I booked a Club room there last year.

The lounge is nice enough - spacious and roomy, and nice views etc.
Breakfast and evening snacks are plentiful and okay; not going to change your life though. Plenty of wine/juice/coffee.. and a small fridge full of local beers to help yourself from. Two PCs with internet. Lots of interesting books on Polish history, etc.
Worth $80.... no probably not, in terms of actual benefits, as you could take a wander towards the old town and eat and drink for much less $, in far more 'authentic' places.
