Thanks to our VP Ken, we have a reservation for July 9th, 2013 at the St. Louis Library Branch: Mid-County Branch
Room: Small Auditorium (MC) for 6:30 PM to 9:00 PM.  Thanks for all the suggestions, but this was the easiest answer in the short term. We're finding that other restaurants have fairly high minimum tabs and that will be difficult to achieve with our small group.

I'll update the web site with all the details over the weekend.
