went to Sunday brunch with my friends.
effective reception service, a looot of tables, relatively cheap dishes, frequent wagon service, choice of tea, choice of dessert.
in one corner of the restaurant, they serve dumplings/noodles/rice/dessert/etc... in buffet style as well. there, you can take your time to check and choose what you really want. otherwise its always recommended to come with your Chinese speaking friends, so you can share a lot of dishes and eat like "professionals".
