On Anon is a great bar/club which is excellently situated right next to London's Piccadilly Circus. I first discovered it on a works do and have been back many times since. It is set over 3 floors and has loads of different bars, most of the time I have been however I have stayed on the ground floor. When the weather is good , if you can get a seat outside it is brilliant sitting there watching the world go by with all the hustle and bustle of Piccadilly circus, it's a shame they don't have more outside seating as it is a great spot. You want to get there for happy hour which I think is between 5 and 8 which is great value, the cocktails are excellent especially the mojitos. I have not eaten here but from what I have seen from other people the food looks very nice and is well priced. On Anon is a good place for all kinds of events/nights out, being works party, birthday, night out clubbing or just a few drinks.
