Thought I'd float the idea to see if anyone is interested.
Probably London and possibly either The Sports Cafe on Haymarket (Trafalgar Sq) or the Carlsberg Sports Bar at the Empire Casino (Leicester Sq) due to central locations and late night opening (East games will run somewhere between midnight and 3.30).
I was thinking that series decider games might be worth the effort and being around fellow fans always helps at times of success (or failure!) although they will be confirmed at only a couple of days notice depending on how a series plays out. (I'd like to boldly state that game 4 of the Celtics series would be my first pick but that could come back to bite me on the arse.)
If there's enough definite interest I can look at booking a table etc.
