I enjoy the DEN club. Granted usually only there in the winter months when out there skiing in CO but it’s a great club for an outstation.
yes nothing special but food is on par with other clubs and the self serve bar is good for a strong pour.
pro tip - going through tsa precheck then hop on the train to A then go to the elevator at the south end of the a station an take it to level 4 and you are right at the entrance to the Skyclub.
