To me Dallas is a city of commerce, but there are little nooks and crannies that you might find interesting. If you are downtown, try Dallas City Hall (I.M. Pei architecture and used in several movies), the sculptures in Pioneer Plaza to the north of the Convention center - then look up at the skyline and find the Pegasus sign. Thanksgiving Square (before 5pm, when they lock the gates), Dallas Museum of Art, the West End, and various pedestrian alleys between Main, Elm, and Commerce streets near Ervay and St Paul.
