My husband and I spent 4 nights in Sonoma County and then traveled up gorgeous Route 1 to Mendocino to spend two nights. Here's a quick report on what we ate to add to the somewhat sparse entries on the area here on Chowhound.
Point Arena- Franny's- this place is worth a trip just for the baked goods- had a delicious salted caramel candy, a piece of layered fudge, and an incredible potato chip chocolate chip salty/sweet cookie.
Fort Bragg- Piaci- not the friendliest or most welcoming place, but great pizzas and calzones to be had here; my spinach/ricotta/mozzarella/mushroom calzone was great. They have a really great beer list (we shared Moonlight's Death and Taxes, yum!) and also a great wine list, which is interesting given how rough around the edges this place is.
Fort Bragg- North Coast Brewing- really down to earth, laidback bar. We got a bunch of samples. Brother Thelonious was my husband's favorite, though we both enjoyed their saison as well.
Fort Bragg- Cowlick's ice cream- a cute local scoop shop, couldn't compare to my beloved Bi-Rite fix I'd gotten earlier in the week, but I really liked the black raspberry with chocolate chips and the black forest (chocolate with cherries). The waffle cone was terrible, so don't waste the extra 50 cents on it!
Mendocino- MacCullum House Grey Whale Cafe- we had our final dinner in Mendocino here. I decided to cancel Beaujolais since we were sort of over heavy and expensive dinners by this point. Grey Whale was perfect since they have more moderately priced entrees. However, they don't take reservations, so we did have to wait a few minutes for a table. Once seated, some live music from a local musician began which provided a nice background. (He was sort of Tom Petty/Bob Dylan-ish with lots of local references in his music, which was fun). Food was very good, simple but better than we expected. We had salad and soup (carrot with coconut and curry) to start, both of which we enjoyed. My husband had the pasta special, which was a riff on beef bourgignon (beef and mushrooms over their homemade fettucine with a red wine/mushroom sauce), which he loved, and I had a burger with fries- tasty meat, but should've asked for it medium rare as it was a tiny bit closer to medium well than the medium I asked for. Dessert was decadent, their "chocolate extravagance," with amazing chocolate cherry ice cream, a brownie, salted caramel sauce, and a big chocolate truffle. Great, leisurely meal.
Boonville- Anderson Valley Brewing Company- our final beer stop of our trip, and much enjoyed by my husband (I was totally beer and wined out by this point so I can't say I enjoyed it!).
I also have to mention the B&B we stayed at because they offer a really wonderful breakfast, which they bring right to your room-- Headlands Inn.
Hope this helps future travelers to the region! Cheers.
