Alas, I suspect Pip is working on that day, even though I gave him strict instructions to get the day off. However, I might be able to get him to tag along for a little while, either before or afterwards. He has weird shifts.
Ok, the gaming place I recommend is in West Finchley. It's called Radicl.
All you have to do, is get the tube to West Finchley, turn left upon leaving the station, and there it is. You can't get lost, because there's nothing else there. We can either meet there, or we can pick a more obvious spot for everyone to meet up and then travel there. I'd like people to tell me which they prefer, since I realise not everyone knows their way around the london underground.
Radicl is open from 10am onwards. I would suggest 10am be our starting time. We have a couple hours gameage, then hop back onto the tube, and it takes us directly to the west end for lunch/hanging out.
I'll see about getting us those free dungeon tickets, and post when I have news. If I can get them, then we do that in the afternoon after lunch.
Then we have the whole of London to entertain us, and London ain't short on entertainment.
