Actually, during my conversation with the German fellows, one of them recommended this place called BRIX http://www.singapore.hyatt.com/sinrs/dini/di06a.html located at the Grand Hyatt, about a 5 minute walk from the Sheraton. He said that it features a great wine and whiskey bar, a live band, and lots of companionships available for the evening , wisely, I chose to retire early without.
