Re: Visiting Pittsburgh from Wales (UK)
Yeah, definitely get a Primanti sandwich and actually, take a walk around the Strip District while you're there, it's a nice place to visit. Lots of shops, a few bars, etc.
Station Square is also really nice, and the fountain show is fun to see. Lot of shopping and a nice view of Pittsburgh at night. You can also take a Duck tour out of there and that is an experience :)
You MUST do the incline. There is the Duquesne incline down the road a bit from station square, and there is also another incline in Station Square I believe but Duquesne is my personal favorite and there's a museum when you get to the top that has a lot of Pittsburgh history. (Do the incline at night too)
