Cape Town is a huge city (population nearly 3 million) with a huge mountain right in the middle. Table mountain is an impressive sight, and can't be missed no matter where you are in the city.
The main city center is all hustle and bustle with various markets (some indoor, some outdoor) on the go every weekday. These markets start up before 8am, and finish up at 6pm. All the usual fast food outlets are here too.
A small bit away from the city center is the Victoria & Albert Waterfront. This is a combination of shopping malls, hotels & restaurants, as well as being the departure point for the Robben Island ferry, and many scenic helicopter flights. Anyone who plans to travel here be warned, that at peak times, the Robben Island ferry can be booked out for upto 3 or 4 days. Unfortunately, I wasn't able to get a ticket.
