Misrepresentation and exploitation by News Cafe

I was having dinner on 12 June 2018 at the News Cafe in Umhlanga Ridge (Gateway) and offered a food menu from which I ordered the Lamb Chops. The price of the Lamb Chops on the menu was R170.00 and when I received my bill the Lamb Chops price was billed as R175.90. I inquired why the difference and I was informed that I was handed the old menu. No excuse or apology was offered and I had to pay the 'new" price of R175.90. Unfortunately your site does not allow to add (insert) the proof of the menu or the bill.( both are available if required). I will report this to the consumer commission and I will further warn potential customers of this misrepresentation and exploitation. I will also bring this under the attention of my friends, colleagues and family and advise them to stay clear of ALL News Cafe's restaurants countrywide.
