Sandton City shopping centre houses some of the best brands both local and international, and if you're looking at just spending a day window shopping, this is a pretty decent place to do it.
From clothing boutiques to tech stores, Sandton City has pretty much whatever you're looking for. It even has a mini casino!
Take a break and grab a bite to eat at any of the restaurants, or catch a movie at the cinema on the bottom floor.
If your feet get too tired, and you feel a little sleepy, you could always check yourself into one of the attached hotels, like the Sandton Sun or the Michelangelo.
