Well, Martlet.
Do you like the Bar Scene?
If you do, Head to the Southside...
Club Cafe has good music and good atmosphere, Fatheads on 18th and Carson has lots of beer imports and domestic Homebrews on tap. They've got a anwesome Menu too.
If you wanna see a Museum head to Oakland and stop by the Carnegie History You cant miss it if you go theyve got a huge Diplodicus Dinosaur out front. On the Northside (Across the River on 7th Street) is the Andy Warhol Museum.
I used to live there, If your staying Downtown, head by River City Inn (On the Corner of Market and Blvd of the Alllies) and talk to Harry the Bartender, hes cool and he can tell ya anything about the city hes written plenty of Pittsburgh Sports and Trivia books.
Another good bar is the Cigar bar and Mick Mcquires (both located in Market Square).
