Drinking Kale Juice at the San Francisco Airport

Love the San Francisco airport!!  I usually bring my own dehydrated kale chips when traveling, but at this airport there's a wonderful restaurant, The Plant.  They have great organic salads and juices. I ordered the kale, parsley, cucumber, lemon (hold the apple to reduce the sugar load) juice.  The perfect drink before a long flight.

Would love to hear your suggestions for healthy travel food.
