Pizzeria La Pantera Rosa

We went on a Friday evening, so fair enough it was busy. We sat down at 9.30pm it was 11.15pm when our starter arrived. We had mussels those we could eat were good, but over half were not opened, therefore not edible. It looked like there were 3 waiting on staff not sure if the blockage is from not enough waiting staff or in the kitchen. The people on the table next to us left after their starter. 1/2 hour after them finishing eating it, their plates still hadn't been cleared with no sign of the next course. All in all very disappointing!
