Poor service at Calistos, Cresta, Johannesburg.

I recently went to Calistos with a group of about 10 people. I have frequented this place previously. Admitted, it was a month -end weekend and admitted, the place was busy. But when you see those that came after you receive their meals before you, it becomes annoying. And just when I was on the verge of paying for the drinks and leaving, one of the staff appears and shows a sign showing that we had to wait another 3 minutes. This was after waiting for 65 minutes. The food was mediocre. It is well said that one should not go to a restaurant on a week or month end, but these are the periods when one has time and/or money. Should Calistos not have catered accordingly. I will not go to this place again and deter people from doing so.
