Yes the CCR is better........more exclusive, and has waiter/waitress service for food and drinks, but there is nothing wrong with the Galleries F Lounge in T3 - it is a fantastic lounge ^
I was in the Galleries T3 F Lounge in March they had i think (i might be wrong) 2 choices of Champagne, one was a Lanson Vintage, and there was also a rose but I cannot remember what it was.
