Leisure Suit Hammy in the Land of the Lounge Lizards
I couldn't let the O2 visit go by without a comment on the "VIP" area. First, it is huge. There are obviously an inordinate number of important people. Second, I confess they do it well. After you enter the gates having tops of water bottles confiscated (it's an elf and safety fing, mate), you then enter the VIP lounge where - apart from being able to buy water bottles, you can buy a wide selection of good food (mostly cooked in front of you) lounge around and prop up bars (as here) At the appropriate time you go up to your private room (with soft seating and a free bar). The room then leads out into the seating, sandwiched between the two steeply raked banks of seating for the hoi polloi. Definitely the way to go.
I know this isn't the best photo with the menu in the way, but I couldn't resist it or the title. Remember that?
