Mamounia Lounge - Mayfair

I was very excited by the opening of Mamounia in Knightsbridge and was hoping to have a good night there with some friends. It turned out to be the complete opposite, I was completely dissatisfied. The restaurant is beautiful and the decor is of a high standard, however, sadly to say the service there was the poorest service I have ever received. There is a high level of favouritism and if you do not have contacts with anyone at the place do not expect to be treated with respect as a customer.
After being seated to smoke shisha we were told that we could only stay for 1 hour which we agreed to. However, 15 minutes later a waitress told us we would have to leave as there was a booking for other people - something they failed to tell us when we arrived. She also told us that we could return when another table becomes available and pointed out that the table beside us have been there for two hours and were probably going to leave soon. I found it hard to understand why they would choose to ask me and my friends, who had only been there for 15 minutes, to leave and not the other table who had been there for 2 hours!! We asked to speak to the Manager, who completely lacked even an ounce of professionalism, and when we asked her this question she simply replied, "We have our reasons". It was clear that there was a system of favouritism. Me and my friends were utterly offended by the complete lack of respect, we were not treated equally to the other customers and you should not expect to be treated as such unless you know some one there.
I would never go back to Mamounia and I would people not to go there too!
