If you are walking in between planes and are looking for that Starbucks coffee fix, think again, as it appears that Peet's Coffee has certainly cornered the market at SFO. Located near Gate 70, in Terminal 3, Boarding Area F, if you are a United traveler, you'll probably pass right by it. Though primarily coffee, Peet's does have some "grab'n go" items, i.e. salads and sandwiches. The staff is efficient and you'll be on your way quickly. The prices are just a bit higher than non-airport locations.
