Tim Ho Wan, named the cheapest Michelin 1 Star dining in both 2010 & 2011. They only serve Chinese Dim Sum and each dish is around USD2.00-2.50. Though all their Dim Sum are good, their BBQ Pork bun is definitely a "must try" item.

The first and the original Tim Ho Wan was in Mongkok district, but it was closed in early 2013. Now they have 4 shops with 2 locations in Kowloon:
1. Olympian City, MTR Station
Shop 72, G/F, Olympian City 2, 18 Hoi Ting Road
2. G/F, 9-11 Fuk Wing Street, Sham Shui Po

and 2 other locations in the Hong Kong Island:
1. Shop 12A, Hong Kong Station(Podium Level 1, IFC Mall)
2. G/F, 2-8 Wharf Rd., Seaview Building, North Point

Warning: The waiting time for a table can be long. Your best chance to secure a table is to get there early and avoid the lunch & dinner slots.
