If you are looking for a great place to hang out while in Rio you must visit Lapa. You can hang out in the streets drinking caipirinhas until the clubs get packed around 1 or 2 am. The stalls all serve cheap drinks and food. One thing I didn't know about the bars in this area is that you get a number when you walk in that acts as your bar tab number. When you leave you have to pay your tab based on what you ordered with your number. Don't loose your number and make suer you have enough cash to pay at the end. Be careful in this area because it is known for pic pocketing because of all the drunk people. This place is a must if you are looking for a great time in Rio!
