Lets all bring some food to share and meet some new people. I can't make thursdays, or wednesdays or tuesdays so any other evening would be great. Bringing our own food (and drink for those who want to) is a good way to keep prices down. I guess its the closest we can get to a great summer picnics, which I really enjoyed, while the weather is cold. The royal festival hall would be a good venue as its the only public place I can think of in London where you can sit without having to spend money.
