My very good friend Evan also joined us from Chapel Hill, and it was really a blessing to be able to hang out with one of my closest friends from the U.S. here in Brazil. We ate a lavish meal at a famous Churrascaria (Brazilian BBQ restaurant) one afternoon and shared many other meals that included Brazilian staples including exotic fruits and, of course, pão de queijo. We also enjoyed a variety of music and visited the famous Municipal Market in downtown Sao Paulo as well as Ibirapuera Park, which is pretty much the Central Park of Sao Paulo.
We stayed in the "Nahu Hostel" in the Butanta section of Sao Paulo near USP and frequently visited the nearby Michelli Padaria (bakery). One of the men working at the padaria was so incredibly friendly and we bonded with him instantly. If the intention was to keep us coming back, it definitely worked because we went back almost every day! The people working at the hostel were really wonderful too. They had a Brazilian BBQ on Evan's first night in Sao Paulo and it was a lot of fun, food, drinks, and lots of conversations.
Sao Paulo was an incredible city, and by that I mean that it was huge! So many people, as the largest city in South America, the traffic was terrible. I don't think I could ever live there, it's really just too big for me, but it really was a cool experience to be there and visit the school (USP) and experience the culture there.
