The Rohnert Park social scene is pretty low key and focussed more on family based activities and restaraunts. The family based idea explains the popular chain restaraunts they are famous for, Chilies, Olive Garden, Red Lobster, El Torrito, Applebees, Bakers Square, In-N-Out... The only place considered a "Hot Spot" I can think of in RP would probably be the becoming more popular restaraunt/Bar/Lounge- Latitude. That place features great food and ambiance.
Residents seem to find their social niche after getting involved on a local sports team, enrolling children in schools, or joining a community organization or facility. In general, the local scene in terms of restaurants/bars/etc is lacking so people tend to venture to other cities nearby for those activities.
