Kalky's is probably the most well-known fish 'n chips restaurant in Cape Town... perhaps even in South Africa! As you can see, the decor is quite unassuming - there's nothing special about the look of the restaurant - which I guess you can then take to be a testament to how great their food must be!
The best time to go would be an hour or so before lunch time - just to make sure that you get a seat. You'll find the restaurant located close to the water's edge, inside Kalk Bay harbour.
And, if you're wondering why it's so empty... it's because this photo was taken a little while after 8am, while the restaurant was closed. :)
