"Yum Cha" and "Dim Sum" tend to be used interchangeably these days to refer to Chinese-style brunch. Yum Cha means drinking tea, while dim sum means the little dishes that accompany the tea. Both are essentials for a typical Cantonese style weekend brunch.
There are just too many good restaurants in Hong Kong for yum cha it's hard to pick the best. But the one I frequented is
Lei Garden 利苑. It is a Michelin star restaurant but it is unpretentious and very reasonably priced. It doesn't give you the hustle and bustle of a traditional yum cha place so it might not be the best place to go if you are up for the nosiness. Another thing I like about Lei Garden is that they take reservation or else it's really hard to get a table in other restaurants during the weekends.
The typical dishes I would order for any yum cha place are:
Shrimp prawn dumpling (Har Gow)
Steamed pork and prawn dumpling (Siu Mai)
Rice noodel roll with lightly marinated shrimp (Har Cheung Fun)
Steamed sweet pork bun (Cha Siu Bao)
Teochew steamed dumpling (Fun Gor)
Congee of any kind
A veggie dish
Stir fry noodle/rice
A dish that goes with my mood of the day
I especially like Lei Garden's Snow Peak Bun (second pic below).
The dumpings or buns usually come in 3-4 pieces in each basket. The above order list can easily feed 4 people.
As for tea, the usual choices are Pu Erh or Jasmine Heung Pin. I personally like Shou Mei, which is a kind of white tea produced from naturally withered upper tips.
Ever since I've turned a meat minimizer, I have often ordered the vegetarian variations of the above. They are equally good.
There are many branches all over Hong Kong. The one in Tsim Sha Tsui should be the most famous.
