In my recent travels over the past few years I'd have to say the most disappointing has been the United Club at EWR by C120. Its large but the decor is dated, the food options bare-bones and unless you order at the manned bar, all they have to drink is water in plastic cups. On the other hand, the new United Club at LHR T2 is one of the best *Gold lounges I've been to over the same time period.
