Calamari served with HP Sauce in a Greek Rest

On Thursday Evening -2 April 2015 we went to Parea Restaurant in Illovo JHB. We met up with friends for dinner. We ordered the meze platter for starter. We had read that this restaurant had excellent calamari so we all ordered calamari. We orders 1 portion of starter squid heads, stuffed calamari and 4 x grilled calamari for mains with Parea's Secret sauce. Once we received our food the calamari was running in black sauce. I tasted it and i could taste HP Sauce. I asked the waiters what was in the sauce and she told me they cook it with Worcestershire Sauce.... I never knew that Worcestershirer Sauce was Greek. Well we all returned our food as non of us at the table could eat our food. It really was disgusting. The manager/owner came to the table with such a bad attitude and demanded that we leave the restaurant - \Pay and leave"was his exact words. When one of our friends went to pay and tried speaking to the owner he threatened him by saying \""I will break your knees!\"" Is this really how guests should be treated? We are all from the restaurant industry and have actually opened up Greek restaurant so the only fool is the owner of Parea! """
