Very few cities have a functional downtown. In the 3 major cities in Ohio, for instance, the downtown areas were vacated when people fled to suburbs. Malls and shops closed, and blocks were leveled for surface parking. Walkability was killed in favor of drives from the suburbs. Aside from one or two streets near major sports arenas with a couple gentrified bars, downtown businesses open for lunch hour and close by 6. I imagine this is the same in much of the U.S. that isn't known for the urban living scene.
