Reply to "Napa Valley trip help!!"

This is an incredibly open-ended question. I would do a little research and then come back with some more specific questions regarding restaurants, wineries to visit, adventures, etc.

Also, we don't know your budget.

Some of the better restaurants in Napa are:

The French Laundry
Ad Hoc
Martini House*
La Toque
Bistro Jeanty
Cindy's Backstreet Kitchen*

Those are all different prices and levels of formality, though. And the only ones I've personally been to are the ones I asterisked.

In terms of "fun places"... Honestly, I like the Jelly Belly factory on the way up north to Napa from Berkeley.
