Really bad service and arrogant Manager

We went on Saturday evening the 13th of January for dinner we arrived at 6 and already I could see service is going to bad as we were sitting at the table for about 5 to 10 min before a waiter arrived. We were 7 people on the table and all went for the sushi special, We ordered our first round and the food arrived about a hour later, hour by we then ordered our next round where by a hour and a half later I sent my son to go and find out where our food is and complain that it is taking ages. After complaining miraculously with in 2 min our food was at our table. In this whole time our waiter never updated us and also we had wine on the table the waiter never filled our glasses we had to do it our self's. After us complaining our next 2 rounds came out a bit faster about a half hour each where after when we wanted to order more we were told that the kitchen is closed now. We also had a instance about corkage on a bottle of champagne and the manger not just un informative but rude as well. This is not the first time that we have problems with the service and food comin out to our table. We are loyal customers that take friends, colleges and family's often to this restaurant for lunches and dinners as the food is excelent but no more, I am done with Villa Bianca and the Fireroom and will make sure that every one knows what sham this restaurant is how bad the service is. I am a paying customer that is told I can get all you can eat sushi but it is actually a **** because they serve so slow that you can get at the most 4 plates and that after you complain. NO NO NO this is not how this restaurant should be, especially as its part of the Fireroom. Until some one tells and proves me otherwise I will not support them any more. I am so disappointed it was our favorite restaurant.
