Major disappointment from begging to the end!

We booked our New year Gala dinner here expecting nothing out of ordinary, civilised nice environment,polite and attentive service and lovely food.We have received none of it! We have arrived around 21:30 due to traffic congestion.We were lead to the table we booked through their portal ahead which was fine.Although restaurant had enough servers just few of them had English.8 course fine dinning dinner set menu was bad at best.Food was cold,bread old,cocktails and mocktails pre prepared not freshly done,gaps between dishes sometimes 15 minutes, waiters forgetting to change dirty silverware leaving you without cutlery, glasses empty not been refilled with water etc...But what struck me the most was the pretentious behaviour of the server who was borderline rude.Live music was not appropriate for the venue.We were literally looking to end this agony as soon as possible and I asked for the bill shortly after. We then moved to the table of the couple next to us to celebrate new year's eve together and found that they had same bad experience tonight even though they are guests of this hotel for number of years.We then wanted to go onto the terrace but doors were locked so I had to ask bell boy to unlock those doors for me which he did, but then he locked us out and we couldn't go back in. From the short time we have spent in the hotel it was evident that there was lack of attention to detail,lack of training,lack of supervision and no management whatsoever.

Apart from the historical significance this hotel has, this is certainly not a 5* Kempinski!
