I know this is quite a long shot but I figure I'd see if anyone knows any Marquette bars in London or if there's a MU alumni group out there that does game watching parties? I'm heading there for two weeks and staying up till the wee hours of the morning would be easier with other Warriors
If there's not a bar that's specifically for Marquette maybe a bar that's known for showing American sports?
Don't know of any, but this site gives the contact info for the Marquette Club of London:

There was a bar on Haymarket, Sports Cafe, now closed, that was a pretty awful attempt at an American style sports bar, kind of like ESPNZone. But I went when I was there in 2012 cause it was a good place to watch football. In one of the upstairs bars, there was a Marquette season schedule poster from Jimmy Butler's last year hanging behind the bar. It was pretty cool.
