The concept is so simple, it boggles my mind that I have never heard of anything like this before. Basically, the whole place is painted white, including all furniture.. etc, they give you markers and you are free to doodle on whatever you like ..ie. walls, bar, chairs...yourself (the yourself part would have been appealing to me in my younger teenage angst days, not sure now.. ha) ..and they serve booze.. so..well that just makes it even more fun. Let's just say, I really want to go to London, yes regardless of the Doodle bar..but I think more so because of Doodle bar.
Here are some pics from their site..
It's so ridiculous that it's great.
