Brazilian Portuguese is the main language that is spoken here.
The Brazilian Real (Reais is how you call this type of money if you want to use it as a plural noun)
A bottle of water costs around R$2-R$5, which is around $0.40–$1.20 USD.
The best meal I've had this week was this interesting Gyuoza at one of the food stalls in the Liberdade neighborhood. Gyuoza is a Japanese dish inspired by Chinese dumplings, but the food here is different compared to the USA. Which is insane to me! I was full after my meal. The two gyuozas I ate were huge. They came with potatoes, diced tomatoes and onions of the same size. This costed R$34.8 or $6.90 USD. A meal in the USA today costs upwards of $15, depending on the area.
So the subway stations play this small jingle every time a train arrives and takes off. I looked it up because it sounded familiar, and apparently, it is a really famous classical Brazilian song called "Carinhoso" by Pixinguinha. It is one of the most well-known and beloved songs in the entire country.
But if that song is too slow, you might like these songs more:
