Starbucks V&A Waterfront

As far the city goes this definitely one of the best spots. Wifi is 100Mbit, the seating is good enough. Music in the interior is bit too loud but it is manageable. It is a busy coffeeshop so expect that noise. The main issue with working here is that the restroom is a couple hundred meters away. It's clean and easy to use but given South Africa's crime levels it is not safe to leave your latop behind so you have to pack up and then come back.
