Disgraceful service at Elements Restaurant

We arrived early evening at the almost empty restaurant for a sit down meal. After 5 minutes I went to look for a waiter who said she would come and help us. About 5 minutes later a waiter arrived to take our food order. Food was good. We paid , we left - not a word from the staff - no thank you, come again did you enjoy your meal? For a 5 star Hotel this is a disgrace - get the feeling the place has deteriorated in d?cor and service. I sent an email and tried to contact John de Canha (manager), his second in charge phoned - very pleasant gentleman and apologetic. said he would email me his contact details - am still waiting - enough said but Beverly Hills will not be seeing us again!! - you can get better service at the Wimpy!
