Without a proper community civic center for clubs and groups to meet, new groups and clubs will need to make due with what is currently available. From the research I have done, the only affordable options are meeting at restaurants. Below are a few location ideas in Modesto. If you know of any places not listed below, please send me an email and I can add it to this page.
Denny's - About half of the restaurants are open 24 hours a day. Currently the Stanislaus County Coin Club meets there. This might be a good fit for smaller groups.
Mountain Mike's Pizza (2720 McHenry Ave, Modesto) - This location has an area in the back that can be used for groups. It is free to reserve, they just ask that people make some kind of purchase. It is consistently busy on the weekends, so more practical to have meet-ups on weekdays.
