Nightlife in Rio

how is the night life in Rio  ?!  and is there any dress code ?!

Unless you're going to an exclusive party, no there is no dress code. Clothes must be clean, pressed and reasonably new. You don't need to go to extremes. A nice pair of casual pants, polo shirt or dress shirt (open colar - no tie) are quite acceptable for men. Women usually choose dresses or a fancy blouse and pants.

Many places to go but I like Lapa ! Google it ! It's a real fun time and many bars to choose from .Go in group if you can but it's pretty safe area.It's always best to take a few Brazilian friends with you.When you go out at night in Rio.Always take  taxi but not the bus !
