Street joints in noodle-crazed Hong Kong

From decades-old holes in the wall to multimillion-dollar businesses, Hong Kong's noodle scene is a money spinner in a city that runs on quick and affordable comfort food.

Steaming bowls are served up 24 hours a day, often in clear, richly flavored broths and topped with fishballs, beef tendon or pork knuckle.

Other favorites come with Spam and fried eggs, an echo of the city's British colonial past.
