Party venue in Richmond?
If you haven't, look into getting a copy of Richmond Bride. It has a directory of "reception sites" in the back, but it also has a lot of restaurants with smaller capacities listed that would be good for showers. You can probably get a copy online at www.richmondmagazine.com
Chez Foushee (neat restaurant that specializes in catering/hosting special events at their restaurant
)Tarrant's (we did a work party there w/just apps and it was really nice)
You might check into Lemaire at The Jefferson
Also maybe Fleming's
I've been to two or three showers at Feathernesters. They do a cute afternoon tea, but no wine.
Barrel Thief, which is a wine store, serves light fare. I haven't tried The Wine Loft in Short Pump, but it seems to specialize in small bites and wine.
For restaurants, I think Cous Cous could handle a group that size. They serve yummy small plates.
That's what comes to mind for small bites - hope it helps!
