London Chess Classic

Say hi to Kramnik for me. I'm sure he knows the philidor position, I'm quite popular among GMs.
Has anyone attended the London Chess Classic over the past week?
I'm looking to go tomorrow and just want to see if it's worthwhile.
Do you get to play any games yourself? I got that impression from the website but it's slightly ambiguous as to whether you have to resigster to play or not.
