Trip up the coast-Looking for suggestions

I am from Tennessee and on Feb.13 my girlfriend meets me in San Diego at a work conference. We are vacationing until the 19th when we fly out of San Francisco. Basically I have to get to San Fran from San Diego in 6 days. I want to do the drive up the PCH to San Fran. I am looking for good food and lodging suggestions. I have done the drive once before along PCH from LA to SF but didn't stop along the way. Here is the itinerary that i have in my head. Feel free to add, subtract, or shoot it down entirely. Restaraunt options are a must. Something nice for Valentine's Day.

13-San Diego
14-Santa Barabara
15-Big Sur/Carmel/Monterey
16-18-San Fran

Thanks
