This is the heart of the CBD, from George Street through Macquarie Street, surrounded by some major retail brands, many restaurants and bars. It is convenient to get to bus stops from most streets and to several train stations. It is also the birthplace of modern trends, and millennials don't pay attention to the people around them. As a result, they hit you every few seconds because they are looking at the phone while walking down the street with an iPhone, not looking at the surroundings.
