Last week, President Obama held a White House State Dinner for South Korean President Lee Myung-Bak. Some of the White House guests for the dinner: Dr. Peter Rhee (Congresswoman Gabrielle Gifford's trauma surgeon) and his wife Emily. The classical music trio, the Ahn sisters. Actor John Cho , looking a little nervous---maybe he needed his buddy Kal Penn. Innovative chef David Chang , owner of the New York restaurant Momofuku.
