Hi...
I advise you to visit the best zone of bs. as. "Puerto Madero"
you should be careful there because this city is very dangeruos.
There are many restaurant, these are very luxurious and almost places accepts credit card,
you can´t smoke here

Now I will talk you of places for entertainment...The Abasto shopping is a place where you can eat, play games, buy cloth, etc., but it is expensive

Well, I wish you good luck

Bye
