Great park for event's! Community Center is where you begin, best of luck.
Call the Community Center in San Ramon.
From what I understand during the winter months the table are first come first access. But you have to share the area if there are other parties around. During spring and summer months you have to reserve the tables. The community center can help with that.
Not sure about it. Maybe you can to the community center on Alcosta blvd & they can guide you further on your question.
