If you don’t mind dropping a couple bucks the new Mustards Grill (of Napa game) in the intl terminal (don’t have to exit security) is actually good. The best UA Club, as others have mentioned, is the rotunda club near the 70’s/80’s gates. agree with what others have said though. Take either the Marriott of Westin shuttle and go walk around bayfront park and have lunch at New England lobster on Cowan rd (walking distance).
