Dressed in blue surgical scrubs and gloves, kitchen staff at an Egyptian restaurant in Damanhour prepare grilled beef-liver sandwiches behind a glass pane as customers see. /Chinanews Photo

The sandwich, a popular street food known as kebda in Egyptian, is the only item on the menu of the operating room-themed restaurant, established in July by a group of Egyptian doctors. /Chinanews Photo

When prepared without proper care, the delicacy often causes severe food poisoning, so the physicians hope to avoid that by applying the same medical standards they practice with patients. /Chinanews Photo

"We tried to take our career values and apply them to this field. There is no contradiction between them. We are still practicing doctors," said Mostafa Basiouny, one of the restaurant owners. /Chinanews Photo
