Oz I think your response got eaten by the internet?
Yes, took so long before I hit the post button that it timed out
My favourite cigar bar in Singapore is The Olde Cuban, right in the busy Chinatown precinct.
It is above a restaurant, and was an opium den in an earlier reincarnation ! To access the lift/stairs you have to negotiate tables of restaurant patrons until you almost reach the kitchen. The air-conditioned lounge is a haven from the steamy heat of Singapore outside. There is a large well-stocked walk-in humidor filled with Habanos, Opus Xs and Padrons. Very helpful and attractive staff on hand to guide you through your selection, if needed. The Scotch list has a page devoted to each distillery eg vintage Macallans back to the '40s. If you're feeling peckish or just want a refreshing drink the staff will happily order you a meal or a whole fresh coconut from the restaurant below.
I can't think of a better place to while away a couple of hours in the afternoon while the wife is amusing herself doing what wives love doing best in a shoppers paradise.
