The building was several different establishments before it was Dorthy 6. Most recently the Karma lounge, which the owner decided to leave the nostalgic front light up sign on the building...prettt sweet. Some other items like the chandelier in the entrance is also from Karma lounge. Like someone previously stated the current restaurant is dedicated to the Pittsburgh Steel industry specifically "Dorothy" which was one of the blast furnaces at the old USS Duquesne/Homestead Works sites that are no longer standing. I myself still work at an operating USS plant Edar Thomson works and appreciate the work that was put into the restaurant for all the added mill value like all the different local steel company logos that were inlayed to the awesome bar top! Also check out "Blue Dust" across the street that pays homage to the Pittsburgh Steel as well, both owners are good friends.
There really is no history on it so much as they picked a theme and built the restaurant
I am not sure of the restaurant's history, but the menu points out that the furnaces at the steel mills were named after women. Sorry I cannot give you more information.
