Well actually the food at the LHR UC is much better (and greater variety) than the buffet on offer at the EWR PL. And the table service dining at EWR isn't particularly exciting. It's usually decent, but nothing like the Delta One lounge. So frankly I'm fine with the bountiful buffet at the LHR club, especially since I will probably eat on the plane anyway to kill a couple of hours on the day flight back west.
