Chau Kee (周記) might have dim sum in its Chinese title, but it's really more of a Hong Kong style…read morecafe that also happens to serve some dim sum items. Their popularity was at an all-time high just before the pandemic and has remained one of Sai Wan's most frequent local eateries.
To no one's surprise, the seating and layout are not group friendly and it can be very cramped. Sharing tables is a big possibility, and I'd come here with no more than 3-4 folks. Waiting is a common past time here, so try to aim for a pre-noon arrival.
Their stuffed toasts are legendary and are indeed the real deal. The salted egg yolk toast is fun to eat and film, but the taro custard (香芋流沙西多士) is next level good. The lava that flows from within makes this the ultimate dessert item, and should be on everyone's table.
Their XO stir fried radish cubes (XO醬炒蘿蔔糕), along with the XO fried rice rolls (XO醬炒腸粉) are two of my favorite items. The dim sum items are fairly standard (especially the shrimp dumplings), but the shrimp stuffed rice rolls are very good. The shrimp toast is not my usual kind of order, but this place definitely specializes in it.
The service is warm and very quick with everything: taking orders, bringing food, and getting the check. Prices are not back breaking but it's a little more expensive than other comparable places. Cash is king.
