Assa Hall - Worst experience in Tbilisi

We went there in June with my friends. The music was amazing and the girl who sang had a great voice. We ordered food and the waiter brought two foods of which I ordered one. I told him that I just ordered one so take the other back. He said i cant do that and you said two, i told him because of the loud music i even showed you fingers of how many i want to order. He talked to the manager and came back and said the manager said he won't do anything!!!!!! When the bill came it was written two so i went to the manager and told him the story and he was the rudest manager i have ever seen in any restaurant all around the world !!!!!!! He said i won't do anything and you should pay the whole price. I said I will only pay for what I ordered thats it. He said back that I will call the police! I told him do it !!! I can't imagine how rude a manager could be! Then after some minutes that he went away, he came back and changed the bill and gave it to us. Worst experience in Tbilisi ! The waiter was so rude and disrespectful and the manager was awful. Don't go there!!!! It's a shame that the band that played there was great and the meals were tasting good but other than that the staff were awful. The manager should be ashamed of himself because of his attitude!
