Focusing on the good: I like all three of the UCs at EWR. They have generally good views, and generally the best food and beverages of any US UCs. The only UC in the system that I frequent that I like more than the EWR clubs is LHR.
I also love the Manhattan views, particularly at sunset (which I seem to hit a lot SFO-EWR). I try to sit left side on inbound and right side outbound in case the runways are lined up right.
