Napa Farmers Market is located in the new Terminal 2 at SFO. It features a wide variety of food, both to-go and food to take home. I have made it my practice to eat breakfast there when I fly out of SFO on Delta. It's an easy walk from Terminal 1 to Terminal 2 and the food options at 2 are better than what is available in 1.
The Tyler Florence booth is in the back of the store. It serves bagels and yogurt for breakfast, sandwiches in the afternoon. The breakfast system is a little complicated---you pay for your coffee in back, then go to the front of the store to pick it up. But the food is good.
Here is my Greek yogurt. It is garnished with fresh granola, dates, and a variety of other fruits. This (and a coffee, of course) makes a satisfying but not too heavy breakfast.
For the ride back, I bought a triple cream cheese. I paired it on the plane with some Boudin sourdough I bought at the magazine store. Wonderful cheese, excellent bread, a very relaxing meal in the middle aisle.
