Downtown Dallas still has the Original Neiman Marcus, the Majestic Theater and the extremely tourist-y area around the JFK Assassination. Downtown Houston doesn't have a department store, open historic theater, or tourist destination that rival those spots, so to a traveller/tourist/suburbanite, Dallas's downtown still might seem like it has more to offer. That being said, downtown dallas has literally 1 decent bar right now: Midnight Rambler.
