Went to this thread from the Chilli crab thread, and since I enjoy dim sum on the weekends, I figured I would provide some inputs. Back when I used to live in Singapore, I enjoy Hua Ting in Orchard Hotel, though nowadays, I would vote for Crystal Jade Golden Palace in Paragon, Orchard Road. I know Crystal Jade is a chain but they are very different and the one in Paragon is special and has won a Michelin star. Some 5-star hotels also have weekend dim sum brunches with champagne where guests can order unlimited dim sum and they can be useful if you want to try everything. Otherwise most reputable Chinese restaurants should have relatively good dim sum.

Another thing to note when eating dim sum is that there are the classic dishes like BBQ pork bun (Char Siew Pau), Steamed shrimp dumplings (Ha Gau), Pork dumplings (Siew Mai), Chicken's Leg in Black Bean Sauce (Feng Zhau), Steamed pork ribs (Pai Kut), Glutinous rice with chicken (Lo Mai Kai), Radish/carrot cake (Lo Bo Gau), Rice roll filled with shrimp/BBQ pork/fried cruellers (Chee chong fun) etc. For authentic taste of these dishes probably the traditional Cantonese restaurants in Guangdong does it better. And as noted by someone Singaporean Chinese are not from Guangdong only, plenty are from Fujian, so there are more modern interpretations of dim sum which are basically like tapas plates. And furthermore one restaurant might do a particular dish really well but another one might be better at something else so it really depends on a particular dish. Some of the modern interpretations found in Singapore are Pan-fried radish cake with XO sauce, BBQ pork in pastry, pastry filled with sweet items like mango and chicken, steamed abalone dumplings etc.

Amongst those I list as my favourite dim sum restaurants, they probably serve a good variation or special dish that I enjoy and do several items well. Of course, there are cheap dim sum that people could enjoy in food courts, since frozen dumplings are even available in supermarkets. So I figured the thread starter is looking for more special dim sum where the chef shows creativity and art in their dishes. As a side note, Singapore has one of the best places to have dim sum outside of Greater China. The other place being Vancouver which has a combination of fresh seafood (essential in many dim sum) and a large HK immigrant population. My best dim sum place in the world, though, is at The 8 Restaurant in the Grand Lisboa at Macau.
