The regular London Smalltalk gathering happens on the first Wednesday of the month, and this month that's tomorrow, the 5th March. I suspect we'll be talking about the more structured event Bryce has organised for the weekend.
As usual the venue will be Counting House:

The nominal start time is 18:00, but people roll up as the evening progresses.
Just in case, my mobile number is +44 772 645 0183
All the best, Bruce
