it's a posh restaurant and service is really good
i went there with my gf on the x'mas eve last year.
definitely need to reserve in advance during festivals as it tends to be overbooked from time to time
food-wise, we 'sampled'(haha) the foie gras and personally I think it's better than any i've tasted elsewhere.
the environment is just as nice; dim-lit and serenading soft music with a view above the boat quay and marina bay.
there are a few pubs/disco at the same floor and you might just party away the night after the dinner.
