Primarily getting to know others in the industry. Getting up-to-date and gaining perspective about things designers are doing these days. And also some interactive conversations/sessions.
How about meeting at a park in the evening (3pm to 6pm)? A couple of us can bring in white boards (if needed) and we can all spend sometime together out in the open.
We could do it at a roof-top restaurant too. Some sort of a brain-storming session. The reason I’m insisting on a restaurant is for food and seating, will be very convenient.
