Chinese Hot Pot
I may be somewhat of a hotpotaholic... I go way too often, and my wallet looks thinner and thinner by the day....
I usually go to Little Fat Lamb hotpot (with the green sign) in Chinatown. I enjoy the variety of dishes, the fact that there could be an individual or a group pot, and the freshness of their lamb and beef.
I'm not sure if they're open boxing day though.
