I hope this isn't too off-topic, but I need my foodie friends' help. We are throwing our 10th anniversary party. Having 40 people for an open house with bluegrass band. Atypically, I have no inspiration for what we should serve. It will be from 5-9pm. Cocktails and champagne. Since it's fairly large I don't want to go overboard on food costs. Can prepare food or buy prepared. Any menu ideas will be gratefully accepted. Thanks!
