Make sure you eat PRIOR to entering the secured area over by US. Prior to leaving the UA area, see if anything looks very appealing in the small food court just before gate 80 (and not far from the RCC). When you don't see anything you like, continue down towards security - the Crab Pot seems a respectable old fashioned restaurant that I have walked by hundreds of times. When that possibly doesn't appeal to you, leave security and make a right, walking to the int'l terminal and see what your choices are in the main part of the terminal. Unfortunately, many good selections are behind security, but there seem to be respectable choices. It should also be a fairly quiet place to hang out, and its a beautiful building. Make sure you eat before continuing the trek to US.
