Wait inside IAH airport after arrival?

Hi y'all, my international flight lands at Terminal D at IAH and I need to wait about 3 hours for my partner to arrive there before we both drive back home to Austin.

Is there a good place to wait after arrival? Any recommendations? I do have Priority Pass access.

EDIT: Here's what my concerns/questions are : (1) will i be able to access any of the restaurant areas after landing? wondering if IAH shuttles people through straight to immigration after an international flight or if there's any restaurants after immigration I can access. (2) if there's no in-airport waiting, what is the best place to wait near the airport (that I could get to and from within 2.5 hours)
