Edit: Sucks that you only have a day, I hear bad things about teh cash games at CC, but there's an awesome club just a wee bit outsie of Copenha. that does tournaments, but it has a 24 hour sign up thing, which means it wouldn't be worth it for you. I'd love to hear a trip report if you do go to the casino, I've considered going myself since I go to Denmark alot.
Edit further:
Vi spiller Texas Hold'em split limit med en table stake fra kr. 2.000 - 5.000.

Translated:
