Too many things to do in Cape Town

I suffer from terrible indecision when looking at long food menus. I sometimes wish that restaurants would just cut down their long menus to the most popular dishes (although I guess that could become rather boring, no so?).

In the same way, there are so many fun things to do in Cape Town that in the midst of all the options it must be really difficult for visitors to our city to narrow down to the few that their time here allows. Naturally most visitors go up Table Mountain, visit the penguins at Boulders Beach, go to see Cape Point, take a ride out to Robben Island, and visit the Winelands of Stellenbosch - but I wonder how many people visiting for two weeks or less go completely off the beaten track. I wonder how many visit Jonkershoek nature reserve, pop in at Betty's Bay, or visit Tweede Tol on the Bains Kloof Pass.

Assuming that you don't live here, what would you do if you came to Cape Town?
