SINGAPORE -- It was a warm Singapore evening and well-heeled diners at the riverside restaurant 1880 were feasting on intriguing-sounding dishes like "Forest Floor" and "Flooded Future." But the real stars of the show were two less flamboyant-sounding mains: chicken and waffle, and chicken bao. When served, the pan-fried chicken was firm and pulled apart tenderly at the touch of a fork. This, however, was no ordinary poultry. It was made from stem cells taken from a chicken feather and grown in special bioreactors.
