Any San Francisco, Sonoma County Suggestions

So tomorrow I’m heading out to San Francisco and Sonoma County, California for a week. Three nights in San Francisco, followed by another three in Healdsburg. So what are the must-hits? The small spot that you love and isn’t the French Laundry? I’ve watched the San Francisco episode of Anthony Bourdain’s The Layover and foresee a lot of time being spent in the Tonga Room. But if any of you Foobooz readers have any suggestions for cheap eats or good drinks, drop a note in the comments.
