You might just need to set something up yourself and see what happens. It's not hard to set something up at a restaurant. You just need to let the manager know if it's a small place.
We do Fuddruckers in NJ because the food is halfway decent and there is a lot of seating and parking. I don't call ahead or anything. I do though set the meet for just after the lunch rush but I don't think high noon would be a particular problem.
It's a good idea to pick a place that is convenient for as many people as possible so a central local is optimal. If you can try the food first if it's not a chain restaurant and make sure there is plenty of parking away from where the masses park.
Make sure you give plenty of notice and if there are other forums in your area invite them as well. We usually get some of the CVN and UPOA crowd and all are welcome.
