The American bar at Mayfair hotel The Stafford had more than the most obvious reason to be celebrating last night.
The hotel hosted a rumbustuous election party and was inundated with people clamouring to drink their way into a new America.
The bar got into the spirit of things by concocting "Barack Bellini" cocktails and "McCain Man of Wars", as well as serving up traditional US-style grub such as hamburgers and apple pie, as well as copious amounts of Dom Perignon of course.
According to general manager Stuart Procter the bar had to employ people to man the door to manage the queue waiting to come into the bar.
"It's been the busiest night of the year...quite frankly the busiest night I've ever had. It was outrageous it went on and on we weren't anticipating that!" he said.
And with a taking of £15,000 in one evening, it seems Barack is already turning around the county's fortunes...
