$100 shiraz sounds reasonable indeed.
Im sure if $100 is a problem then you'll find the food a problem as well lol... Please elaborate because you seem you're more interested in promoting the other place.
Go to the corner kopi shop and u'd pay for a bottle of water these days :)
actually, the better places serve red wine slightly chilled. room temperature in singapore is actually a bit too warm for wine. For $100, what did u get is the question? Wine is often quite subjective. I also don't think you should write off a place because they don't serve tap water. How's the food? You say it doesn't justify the pricetag. What did you have?
