Historical version 1 of Royal China, E14 8RR
Chinese Restaurant in Canary Wharf. Notable for the very good dim sum served (a la carte) at lunchtime, which ranges from the usual tasty dumplings to more exotic dishes such as duck's tongues or chicken feet. Vegetarians and vegans are nonetheless well catered for, too.
There's seating outside, which is very popular during the summer; however, it can become very busy at lunchtimes at any time of the year, and booking in advance is advisable.
Their website is Flash-based and quite maddeningly awful.
