Nope. There is a pre-flight dining area which looks salvaged from the T4 CCR however. Champagne is now placed out near the chef's theatre, so I recommend you get your money's worth. But all the good booze has been decamped to the T5 CCR (and not, indeed, the Galleries First). The atmosphere in the terminal itself is eerie and unpleasant. Dead dead dead.
If originating the trip in London, aim to arrive as soon as possible to departure. Fortunately, security should be a breeze.
