Years ago when I belonged to Toastmasters several restaurants would reserve "side rooms" for small group gatherings. Maybe if you had a consistant Saturday each month you could get people. Like last Saturday of every month at 9am. Henrietta seems somewhat central. Trying to accomodate schedules and changing dates and times would get confusing and would be a pain. Whoever can make it comes. You could get someone to give a 10 min talk or presentation during breakfast. I agree that swaps are not very social.
