I have been here many many times and overall my experience is very good.  They have a good selection of drinks and decent food.  They mac-n-cheese dishes are delicious and so are their burgers (my favorite used to be their sliders but unfortunately they removed them from their recent menu). The ambiance is also great for both winter and summer (they have outdoor patios), while the service has always been friendly and useful.  I am sure I will be visiting Harris Grill quiet a few more times in the future! A good choice if you find yourself on Elseworth or Shadyside in general.
