Ching-He Huang is headed to Kansas City, Mo., to a family-run Vietnamese restaurant. Mimi Perkins opened Saigon 39 to rave reviews and lines down the block. Now, over 20 years later, the restaurant is in the hands of Mimi's children, Linda and Victor, and business has plummeted. Although officially retired, Mimi is still the boss. Ching needs to bring the dishes and the decor into the 21st century and get Mimi to take a step back and let Victor and Linda run the restaurant.
