As London steps a little closer to New York, hotel restaurants are shifting from an afterthought or an annex, into places to hang out at, even if a room isn’t in scope. Even before Florence Knight’s new opening, Lunette, anybody who’s anybody has been clamouring to visit Café Clement at Nick Jones’ Strand hotel. Nigella Lawson’s been more than once and it only opened — softly, I should add — in June. Stanley Tucci visited with Angela Hartnett almost as soon as the doors opened. Oh yes, savvy marketing has been employed, but these people don’t have time for nonsense even if it’s free.
