I don't know about the SAS lounge in CPH, but the Gold lounge at ARN is very large and nice with lots of fresh food. The SKF lounge in SIN is a favorite, but not technically a Star G lounge since you have to fly F to get in. I'll be trying both the Star G lounges in KUL and BKK tonight. Hopefully I can manage my way into the TG F lounge. I've done it before at Don Muang and loved it. The Star G lounge at Suvarnapoon is nice though.

Lots of other nice ones that I can't think of off the top of my head.
