Recs/Tips on places to visit for a day trip to Napa Valley

[thing1thing2]

Parents are visiting next weekend, thought it would be nice to spend a day in Napa. They're not big wine drinkers but thought it would still be fun to visit a winery and walk around the area.

Any recommendations on how we can spend the day there? Will do lunch/dinner and visit a winery, but that wouldn't' take the whole day?

Also, any recommendations on which winery we should visit?

http://www.castellodiamorosa.com/ is a fun place to visit. The tour takes like an hour or so and the wine is pretty good.

http://www.adhocrestaurant.com/ is a good place to have lunch. Its from the same guy that owns French Laundry and Per Se.
