Pennsylvania

Great burgers at Burgatory and Hyde Park has the cloth napkins and early bird dinner special before 6pm. Both located between the football field and the baseball park and very walkable from the north shore hotels.
A little more of a walk would be up to Manchester neighborhood and the Modern Cafe and Nicky’s Thai Kitchen. Manchester is less than a mile northwest from the Hyatt Place hotel.
And directly north would be Allegheny Commins and the Federal Galley with several smaller food court eateries. Beyond the Commons there is 40 North on North Ave which had some great sliders on the bar menu when I was there last winter.
Tell the wife welcome to the North Side and hope she has a nice visit.
