I don't know the venue. I'll ask them, maybe they don't have it confirmed yet.
Last DCF I attended was on a Gym nearby O'Connell St, so it was quite centric.
About the time, I asked them to have some "space" (there will be no stage, so it will be just a table and a few chairs) around lunchtime (that is, around 13:00) So far it looks like that will be the time, but still is not confirmed. As soon as I have anything else confirmed, I'll update the post.
