For drinking, ask for guaraná (gwa-ra-NAH; soda made from the seed of an Amazon fruit, also available as a strong drink), mate (MAHTCH; sweet ice tea; not like Rio Grande do Sul or Argentina's hot and sour mate), água de coco (ah-gwa-djee-KOH-ku; natural coconut water) or caldo de cana (caw-do-djee-KAH-na; sugarcane juice). There is also a common fruit called açaí (ah-sah-EEH), with a dark-purple pulp out of which are made juices, and ice-creams. Typical cariocas eat it like cream in cups or glasses, mixed with granola, oats or other flakes. The best place for such drinks are one of a number of Rio's open juice bars. Very often, these are located on street corners and have long, curved bars offering you juices from pretty much every fruit you can imagine. The best option is a small chain of juice bars called "Big Bi's". The juices are astounding value alongside their good selection of salgados and sandwiches. Their açaí is one of the best in terms of value and taste and the staff are excellent. On top of all this, if you leave a tip, you get a big "Obrigado" from all the staff. For the best Big Bi's experience, try the Tangerina ao Limão juice along with the famous Bauru sandwich for a total of a mere R$13. Finish it all off with an açaí to go. Perfect. Big Bi's has a few branches dotted around Copacabana and Ipanema, one of which is on the corner of Rua Santa Clara and Rua Barata Ribeiro in Copacabana. If you then cross the road of Rua Barata Ribeiro, you will land at an exquisite ice cream parlour.
