Where to go for good shopping in Johannesburg?

Hello,
I am thinking of taking a trip to Johannesburg in a couple of months and we would really like to go shopping there. It is one of our favorite pastime activity ...We were wondering is there anyone who could tell us what place is good for shopping in Johannesburg. Thanks a lot in advance!

Hello,
You are my man, or should I say my woman. I have just returned from Johannesburg girl, and my I tell you is one hell of a shopping paradise. My favorite mall was Sandton City located in the business center of the city. There were many more mall all around the city and they are really good!
