Best food served fast in terminal 4 concourse B near gate B9- I have had the Napa Salad for lunch and the breakfast burrito for breakfast here and both were excellent.  They also make great cappucinos.  Most of the restaurants in this terminal all had salads premade in plastic boxes that looked identical.  Press Coffee made the salad fresh and it was outstanding.  Furthermore, the staff was friendly and helpful, which was the reason I first ate there, after waiting a long time at the place next door for a cashier that did not appear happy to be at her post.
