You will also be benefiting from the complete collapse of the ZAR...congratulations on your timing Accommodations in SA are not all that cheap by developed-market standards, but food is stunningly inexpensive even when the currency is trading at normal levels. At this point you will feel like a millionaire.

If you are in need of a casual meal in CPT, I can also highly recommend Cafe Paradiso on Kloof St. Excellent food, good wines by the glass, very friendly service. They have a lunch buffet (which is dramatically better than it sounds) that fed three of us quite well for something like USD 18...including two glasses of wine and one lemonade. Not a typo!
