Do you have the U.S. Bank Altitude Connect card (they also make an Altitude Go card)? I just logged into the Priority Pass site with my associated Altitude Connect PP membership card. When I search for airports with restaurants such as IAH I am seeing places listed. But, if I login to the the Priority Pass website with my Chase Sapphire Reserve (CSR) membership I am not seeing them listed, so that tells me that the the Altitude Connect has the benefit.

The nice thing is that if you have multiple PP memberships you can login to the site to see what access you have simply by searching after being logged in.

I am planning on testing this soon, but have not had a chance since I got this card a few months ago and have not flown to a airport with associated restaurants.
