I am a newcomer to the Chowhound community and this is my first post, so please be gentle if my questions seems silly. We are going to Napa for 2 nights in May and then 3 nights at the Ritz Carlton. I have been pouring over the boards the last few days as I start planning our trip and have found it to be a wonderful source of information on restaurants and general SF area info. I would like to have dinner at Chez Panisse but will not have a car while I am in town. Is it a reasonable cab ride or is there public transport available?
