This is a largely social gathering, for the PIEs 'community' in and around London. It is simply a meal together, for any who wish to join; and a free flwing conversation..
There is no cost, other than the cost of the meal itself. We use the eventbrite booking system only so that we have some idea of numbers, and can then book a table or two.
We have given Trafalgar Square as the venue, simply because Eventbrite software needs a location. In practice, we will change that detail here, closer to the time, when we have an idea of numbers, and our table(s) booked.
