Safari nursery restaurant: false advertising

Please think twice before you decide to eat out at Safari Nursery in Pretoria East. Friday 4 December 2020 me and my colleagues from work had our Christmas get together at Safari nursery. We budgeted according to their menu published on their website which were reasonable and affordable. When we got there, we saw that the prices on their menu were triple what it was advertised for. The manager informed us that the menu on their website has the prices of the year 2012 and they are not able to update or remove it. I told him that by law you have to charge the prices for which you advertised a product. The manager said he is aware of that and apologized and offered us 20% discount. After we ate, and wanted to pay, he informed us that the owner overruled him and we will have to pay the full current prizes. I told him that we are left no choice to pay, but we are surely taking it further as we are not satisfied with their decision. We are taking the matter to the consumer board. We were deliberately misled by false advertising and again by the manager and owner of Safari Nursery.
