wich cities are real "megacities" in your ey?e

We all know , megacities are cities with more than 8 million inhabitans (UN definition) ,there are also alot of megacities ! but for me a megacity is more a.) urbainaty flair (culture ,cinemas , restauranst ,etc..) b.) finance (stock markets , finance jonglours) b.) headquarters ( Daimler benz,Deutsche bank, merril lynch etc... ) d) a good infrastructure (streets, highways , underground and an airport) so for me real megacities are Sao Paulo , NYC ,Tokyo ,London,paris,LA Tokyo,Shanghai Chicago ,Toronto,milano and Osaka>
