All in all a decent star alliance club. Not quite up to par for a "hub" location as compared to the NW/DL DTW clubs or the UA SFO locations, it's still pleasant and quiet. (BTW this is a club in the B terminal.)
As a European Star Alliance Gold member I can get access even when flying US domestic. In the US when flying domestic First you do not get access to lounges. You have to buy memberships or day passes.
