Pittsburgh is an awesome city. Of course, I lived in the area until 2000 (and return a few times a year to visit family and friends), so I'm a bit biased. Yes, I grew up saying "y'inz."
While it's a bit lacking in transit options (limited rail, a bus system that leaves much to be desired), downtown is usually hopping. Naturally, the place is busy during the day, with major business entities (Yay Heinz katsup!) making homes there, Pirates/Steelers/Penguins games always happening, and a few universities. There also are plenty of cheap and free events, especially during the summer (their art festival is one of the greatest, and the radio station and bars often close off side streets for street fair type deals with vendors, food, etc.). And the gorgeous tall buildings... it feels like a city should, "dirty steel city" image be damned.
But even at night, there usually are people out and about, checking out the restaurants and, yes, even shopping. I don't remember super-late hours downtown, but I do remember going to Kaufmann's in the evening
(edited to add: The highlight of shopping for a homecoming or prom dress each high school year was going to the downtown Kaufmann's. It usually was girl bonding time, with me, my mom, and either my aunt or my mom's friend from work.). I'm sure the 10 p.m. thing goes with the holidays, but it's always nice to see a city keep its life in the evening.
Oh, and yes, there are a lot of loftworks going up and old, historic-type home renovations taking place. I love it, and I can't wait to eventually go back to live (no offense to St. Louis, which I've also come to love).
Edited to add: A $300,000 loft renovation (old two-family, three-level building that they converted into a personal loft) in one of the "poorer" inner 'burbs that's seeing an infusion of community, business and life was profiled sometime in this past year on that "My house is worth what?" show. The $300,000 price is what it's worth now; they paid like $100,000 for it. Pittsburgh home prices are awesome. Oh, and the owners were a former pro-football player and his wife who shunned the suburbs to be close to the city.
By the way, if you're in that area of the country and are heading to P'burgh, be sure to head downtown via I-279. When you pop out of the loooong tunnel through the hill and find yourself suddenly on one of the city's bazillion bridges, it's seriously is the best reveal of a city ever. Absolutely stunning.
God, I can't wait until I go for the annual holiday visit.
