The first Cincinnati chili parlor is Empress. Go there for the 'original' taste. In 100 words or less, Gold Star's taste leans more towards the meat, Skyline's taste is more towards the spice. Polarize yourself accordingly. Empress, IMO, has the best blend of the two styles, but all 3 will provide a tasty way to fill up for cheap, provided you like Cincinnati-style chili to begin with. If you don't, why waste the bandwidth here?
