Pathetic Customer Service

We recently decided to go out for the Night out for 2 at Silverstar Casino and 1 of the Restaurant Choices were Vigour & Verve and they had what seemed to be the best menu from all the options. No where does it mention that you need to make a reservation for a table on this special and neither were we told about it as well. We went and stood in the line for a table and after about 20 mins we approached the Manager to ask what was the delay. There were 5 tables that were free and not 1 time while we were standing in that queue did anyone bother to come and let us know what is happening. The Manager then tells us that they are fully booked and the kitchen cant keep up with the orders. They refused point blank to help us in anyway and on top of it gave us an attitude. Im sorry but if you know its going to be busy, you need to up your game or put a sign up or at least COMMUNICATE! The customer service is PATHETIC. To top of all of this, a couple from the back of the queue skipped the line, sat on one of the 5 empty tables and immediately got served! The staff could not care that we were upset or bothered with us at all! This is disgusting service and looks like bribery and *******ion with the Managers are the way to go!
