I joined expat.com on 21 September 2017.
São Paulo is a cosmopolitan city and works 24/7. If you want to have american style breakfast, have lunch in a chinese restaurant and have dinner in a mongolian restaurant, all in one day, it's possible. Also, everyday (in different locations) have the street market, where you can find fresh fruits, vegetables, various meat (fish, chicken, pork, ox), flowers and local foods.
Like any big city, São Paulo have bad traffic.
