Haven't been, might go soon, but wanted to past the tips along in case other hounds are more hungry.
New branch of Scoop opening soon in South Kensington, I don't think they've taken the wraps off yet.
Antico, an Italian restaurant/bar, on Bermondsey street just opened its doors recently (just down the street from Zucca). Menu looks pan-Italian rather than region-specific.
Pinkberry, the frozen yogurt chain, opened a branch in Selfridges food hall on Oxford Street.
P.S. just enjoyed a meal at Tao Tao Ju, a new Cantonese place in Chinatown on Lisle St; will post soon.
