Baby shower locations around Gettysburg?

I'm looking for a location for a baby shower in the Gettysburg area. My friend called a winery in that area and they wanted $200/hr to rent their room (for a group our size they said we couldn't "just come and do the tasting"). I'd really like something nice and open and something like a winery. The mom to be doesn't like being the center of attention so we want to make it as low key as possible.  We are also looking at 30 to 60 people so we'd like to be able to bring our own food and wine/champagne.  Thanks!
