Chinatown kitchen supplies
The best selection Ive seen in Chinatown is at a little hardware store on Wentworth. Im afraid I cant give the name or exact address but its on the west side of Wentworth (200 W) a block or two south of Cermak, so about 2350 S.
On the north side, Broadway Supermarket has an aisle or two devoted to cooking utensils.
Another place to check is Chicago Food, the huge Korean market. They have a room of non-food items with a particularly good selection of plates, bowls, etc. They also have some less common things like real stone pots (for bibim bob) and large pottery crocks (for kimchee).
