Farmers Market is not a cafe, it's a store, there is nowhere to sit, you grab your snack and go to wherever you need to be.
They sell pre-packaged salads and sandwiches, like hot tuna, made from albacore tuna salad, pickles, tomato, romaine, spicy sriracha aioli, on rye. Also your typical snacks and chips of the Kettle variety, as well as baked PopChips, nuts, pre-packaged popcorn.
To wash it all in, there are health cautious drinks like Naked brand fruit and vegetable juices, Tropicana, Horizon organic milk, coconut water, and sodas like Coke, Dr Pepper, Sprite, Honest and Snapple teas, Gatorade, Monster energy drinks, and FUJI bottled water that I happen to like.
Also saw some fresh fruits of a shelf variety like apples and pears. Overall, I'd say these are way better and healthier options than your regular airport snack stand. An individual carton of organic milk will go a long way in terms of making wise choices while traveling.
