Really bad service

I attended an Event at Rumours on Saturday and, while the Event was amazing, the service levels at the venue were less than wonderful. They were short staffed on the floor and behind the bar resulting in a wait of up to 30 mins to just get a drink and our food order took 45 mins to arrive and was wrong and then there was another hour's wait for the replacement. When the bill came we were still charged for the wrong order. I don't think that the staff was to blame as they were completely overwhelmed.
