Aqua Shard is in two parts: a smart, fine-dining, expense-account venue with magnificent views, and an attached cocktail bar with equally fabulous views, reviewed here.
Aqua Shard is itself only one part of the Aqua Group's premises set halfway up the Shard. Hutong, a fine-dining Chinese restaurant, is on the floor above (and, of course, also has terrific views).
The Aqua Group is a Hong Kong-based company, best known for its well-regarded and very stylish restaurants in Hong Kong, including the original branch of Hutong. In London they also run two attached restaurants just off Oxford Circus, Aqua Kyoto (Japanese) and Aqua Nueva (Spanish).
