Got this from a friend of mine, it's the cheapest Michelin one-star restaurant and it's in Hong Kong.
Tim Ho Wan, which means Add Good Luck, can seat only 20 people in its steamy dining room where battered bamboo baskets of dim sum sell for as little as $1.42.
Oh, in Chinese it's 添好運. It's address is: 2-8 Kwong Wah St., Mongkok. 2332- 2896.
Mmmm, would love to try it, but the queues are an hour long at times, probably not somewhere you want to go to if you are really hungry.
