Sadly, the Centurion Lounge has abandoned its original intent: an exclusive lounge for Centurion Card holders. The first lounge, I believe, opened at Las Vegas and was an exclusive oasis: offering top end drinks (I recall Johnnie Walker Blue Label being available for self-serve). The dining options were an array of dishes, freshly delivered, from the celebrity chefs of the city's finest hotels and restaurants. I am fortunate to have visited that lounge several times; before the doors were flung open to all and any Platinum Card holders. Now, the only advantage to a Centurion Card holder is complimentary champagne. Food has become a ubiquitous chicken melange of little merit. Priority Pass serves me better now. That said, most UK airline and third-party Lounges far surpass their US counterparts. I shall hope to find a recreation of that original Las Vegas Centurion Lounge arising in T3.
