CPH is more or less a primary non-US airport for me, and I continue to use the Eventyr lounge a lot.

The Eventyr lounge is my preferred lounge at CPH — in terms of food, in particular, but also because it’s the only lounge on the non-Schengen side of the CPH airport. Even for my SAS TATL trips out of CPH as a Star Gold entitled to SAS lounge access at CPH, I often aim to use the Eventyr lounge courtesy of Priority Pass.

The other PriorityPass lounges at CPH are a big step behind the Eventyr lounge. But, unlike with the Eventyr lounge, they happen to be on the Schengen side of the airport.

The CPH airport has Metro train service from the airport above ground. There is also the underground track service at CPH that also serve the border crossing trains, but those trains from the underground tracks run less frequently than the Metro trains and have fewer stops and a different routing than the Metro. Use the Metro instead, even as the Danish public transport tickets for CPH to Copenhagen zones also work for using the (non-SJ) trains below CPH to get into the city center.
