It's too hard to review 'O2'....there is too much to consider! Our experience going to see Paul McCartney was excellent... the train in was good in & out....we got drinks ok...didn't queue really for entry / bag searches...had booked good seats with toilets near..etc etc....good 'new' things were full plastic bottles of wine & Camden IPA (which hadn't been delivered but at least it is coming).
