Pittsburgh's South Side (Flats) is a 30 block long (right across the river from center city) historic district - one of the longest Victorian main streets in the US.
People live, eat and drink there. With approximately 70 bars and taverns, the neighborhood is patroled by Pittsburgh Police public urination patrols. Amongst the many shops and and stores you can find fine dining, get a tattoo, buy Versace clothing or idle away some time at one of the many coffee shops - all locally owned and operated.
The South Side is a very diverse and rather funky place.
