Every year before the Chinese New Year Break, companies hold a "weiya" banquet for their employees. There is a several course meal (we had at least 10 dishes) and nice door prizes (everything from cash to a washing machine) handed out raffle style.
Oh, and all banquets in Taiwan (every one I have been to and seen, including wedding banquets) have people sitting on (red) plastic stools in groups of ten at round tables covered in pink table cloths--usually outside. There were probably 20+ tables at our weiya, so that means around 200 people participated. A benefit of sitting 10 to a table is that foods can come in groups of ten--ten stuffed mushrooms, ten little lobster trays.
