My fiancée was getting her hair styled next door, so I stopped in for a few beers to keep myself entertained while waiting for her. Charlie was bartending and was very friendly. No one bothered me as I played UNO on my phone and drank my beer. At one point, I cashed out to go meet her stylist. When I came back, Charlie remembered me and the beer I had been drinking.
The décor was decent and it was amusing to watch a replay of the Winter Olympics from the viewpoint of the UK. I would not make a special trip to Big Ben, but I would definitely stop in again if I am in the area and looking for a beer.
