Woodfield restaurant sued

A woman has filed a personal-injury lawsuit against a Woodfield Shopping Center restaurant, seeking more than $50,000 in damages from broken teeth caused by what she says was a rock in her food. Yeo Kim filed the suit against Todai Restaurant and Chicago Sushi Seafood Buffet in Cook County Circuit Court Tuesday. The suit says the incident occurred in July 2008. Representatives of Todai Restaurant's corporate headquarters in California said the appropriate person to respond was not available Wednesday.
