Come mealtimes, there are always long queues outside this Hong Kong dim sum chain, likely generated by its Michelin star and the relatively low cost. To avoid a horrendous wait, come on a weekday after 2pm. Try the transparent spinach dumplings with shrimp. Food is cooked in lard, so no good for non-meat eaters.
There is another branch of Tim Ho Wan in the Shin Kong Mitsukoshi mall (or Building A8) on the pedestrian strip in Xinyi.
