Can anyone recommend a venue, such as a park, coffee shop, free gallery of some type, etc... just about anything would do, I think, but I'd prefer to avoid actual restaurants as I don't want people to have to pay over $5 to participate... which would be suitable for an early afternoon small group meetup, situated in the east Bay between approximately San Ramon and Pleasanton? (Castro Valley/San Lorenzo area less desirable, but might work.)

I see there are a number of regional parks but I think I may want something a tad smaller, where it might be easier for people to find each other because the exact location to meet is more obvious (and since I haven't been to any of them, I can't give a description of a specific landmark to look for).
