sorry Yvonne, but what do you mean by food rate??
i have not had my food tasting yet, so i cant comment much... however, the remarks on the forum seems to be quite good for the food quality.
they have one grand ballroom at the first floor (Fan shaped), i think three small function rooms on the first floor as well (not too sure whether can open up the rooms or not), and there is a smaller room on the 5th floor, the Ariels Taipeng suites.. been there last week, venue is quite nice, pretty cosy..
