Hi Juan,
I'm not sure about the ambience or the layout cos i had never been there before, just read about that particular wedding at fatty weng in a bridal magazine. I dun think fatty weng provide a wedding planner cos the couple did it themselves. they wore those traditional wedding costumes (those you see in period dramas -- huanzhugege type) and marched in to chinese opera. As their wedding was during the mid-autumn festival, they hang lanterns and had lanterns as the centrepiece.
I'm thinking of doing a chinese theme also (that's y i kept the article) but more of those 1960s type like hua yang nian hua like that. Thinking of doing the second march-in on bicycle (hubby cycle then i sit behind).
I think the ambience you can create it yourself. We can't possibly please everyone during the wedding.
