Some like it slow, but you? You like it fast. And easy.

Without remorse.

Thankfully, you no longer have to feel guilty about eating fast food: Alan Yau, the man behind Hakkasan, Yauatcha and Sakenohana, has a new venture that’s all about speed.

Opening today is Cha Cha Moon, a walk-in Chinese noodle bar with open-plan kitchen and communal seating similar to Wagamama and Busabai Eathai (also part of Yau’s empire). On the menu: crispy duck lo mein, char sui ja jain udon soup or Peking-style noodle soup — all of which appear in a flash.

Yau plans to open a second outlet in Whiteleys shopping center later this year. But because you’re an impatient so-and-so, you’ll want to check out the flagship first.

So do it.

Fast.

Cha Cha Moon, 15-21 Ganton Street, W1F 9BN (020 7297 9800).
