Royal China (Raffles) - Good Standard, high price, variety wise not alot.
Taste Paradise (ION) - Good Standard, high price, fusion creation dim sum like foie gras xiaolongbao
Boss (Vivo) - nice deco, good price, good presentation, constant and good standard
Hai Tien Lo (Pan Pac) - expensive and very quiet, nice view, food is good.
Old Hong Kong (Novena) - Pretty good, small and crowded, but some of the dim sum not very nice.
Wah Lok (Carlton) - Good food good pricing, not crowded.
Wah Ting (orchard) - above average food for high reputation, still good but not impressive.
Buffet
Jing (One Fullerton) - award winning chef, good place if you eat a lot, above average standard.
Jade (Fullerton) - similar to jing except it is pure dimsum, price cheaper by $10 but need around 2 months of booking.
Crystal Jade can forget it, too many branches cannot keep up with standard, mostly central kitchen except the Gold Palace, but the tables are very near to each others.
Imperial Treasure still ok, manage to maintain for the Ngee Ann outlet.
Hai Du Victoria peak (Orchard Central) - worst then the main one in HK, nothing fantastic.
I-Canton (ION) - gives a false impression that it is from HK but it is actually from Malaysia. Ugly Deco, over-priced average quality food. walk over to Taste Paradise which is just a few units away.
Victor's kitchen (sunshine) - cheap and good dimsum, it is a small eatery but can be very crowded.
still a few more but either they are not worth the high price or they cannot impress me.
