Okay, so that's the Greentree/Carnegie/Crafton area.
If you want/need to go out to breakfast, you can try Bob's Diner or Gab n Eat in Carnegie. If you want to risk having terrible service, there's also Eggs r Us in Greentree.
Friday night -- if you're staying near your hotel -- check out Carnegie. Some decent bars and restaurants in that area. If you're going elsewhere, check out the following websites for what to do/where to drink:

The above have some good lists/maps.
Saturday, I would suggest going downtown (Market Square) or near the stadiums (North Side/Shore). I like The Yard in Market Square and really want to check out the Southern Tier that just opened on the North Shore.
Last note: taxis/Ztrip in Pittsburgh are extremely unreliable. Try Uber or Lyft.
