Vat charge not included in the menu price

We are from Joburg, we visit Umhlanga regularly and we make it a point to eat at Circus Gateway. We recently visited and were excited to find Circus at Umhlanga Village on Cartwell Road. The menu was regular and fancied the pork ribs that were quite pricey for 500g when compared to other restaurants that have ribs as a speciality. Our disappointment was when we were presented with a bill with had a Tax charged separately and when we inquired, the waiter could not explain what tax it was and she claimed she was not aware of it. We also explained that our surprise was that nowhere in the menu it says the quoted prices do not include Vat which we thought was ******* in SA to not highlight that fact. So, my advice, anyone visiting Circus, please check your bill and what taxes are charged after the fact - for us, we will never been seen there again, they seem dodgey.
