I need to plan a dinner for a large (75-80 people) business group at a winery in the Napa Valley. Right now I'm considering Pine Ridge, Domaine Chandon or Rubicon. Has anyone had any experience with the dinner parties at any of these wineries? Or do you have other recommendations for me?

Had a smaller dinner party, about 20, at Domaine Chandon and it was great. Good service, food & atmosphere. No experience with the others.

I suggest you post this question on wwwtripadvisor.com
in the Napa forum. They have several people over there who are in the business and are on there daily.

Thanks-good idea

A number of wineries can provide catered dinners for business groups. Robert Mondavi is probably the most famous one. Also, some of the newer wineries with caves offer their space to groups for lunch or dinner. Dining in a cave or barrel room is very memorable. Two that I've dined in that were impressive are Silver Oak and Far Niente but I'm not sure if they rent out to groups that are not wine related.

There's little or no info about this on the web so it's best to just call the wineries you would be most interested in dining at and see what they have to offer.
