Ask one of the hotel staff which dim sum restaurant they would recommend, one that locals frequent, not a hotel version. Get it written down in Cantonese, and have a cab take you there. Remember to also take something indicating your hotel address for the return trip. Even with language issues, you'll have an interesting meal. No menus - order little plates of various nibbles from carts as they wheel by. Might have to work a bit harder to order a good shark fin, bird's nest, or winter melon soup though. Meqal can go on for a good long while. Great meal to linger nad visit with new/old friends. Dim Sum is the hongkers equivalent of entertaining friends - they do it at restaurants instead of in their homes.
