The Year of the Ox is upon us. Apparently the ox is the sign of prosperity through fortitude and hard work. In the spirit of being prosperous, the Chicago Chinatown Chamber of Commerce is offering a downloadable and printable 15 percent off coupon that is good at 11 Chinatown restaurants now through Feb. 13. Participating restaurants include Dragon Court, Evergreen Restaurant, Hing Kee, House of Fortune, Kam Fung Restaurant, Lee Wing Wah, Lao Shanghai, New Three Happiness, Won Kow and Furama Seafood Restaurant. Visit the Chinatown Chamber web site for a list of the restaurants' addresses and phone numbers. You can only use one coupon per visit, but you can download the coupon multiple times for multiple visits at the various restaurants; it's not good for parties of 8 or more. Let's hear it for the ox!
