Dros Gateway Worst Service ever

Table Ordered food, calamari starter sent back three times as the calamari was raw and the wrong food was ordered. We then ordered 2 peri peri chicken livers where the bread was old and we had 4 actual chicken livers on the plates. Astray was not removed once since we sat down at the table. Also bad attitude from the servant was recieved, the manager tried to discount the bill. But they only took off one plate of food.
