This site on Wardour Street in Soho had seen many bars and restaurants come and go. The latest occupant is Princi, an up market Italian bakery brought to London by Alan Yau (of Hakkasan, Yauatcha fame).
Natural stones, polished brass and water reflections dominate. The long communal tables (de rigeur for any Soho eatery), leather upholstered chairs and perfect lighting make this a stylish choice for a slice of cake (made from organic "00" flour) and a caffé machiato from the Italian barista (yes he is, I talked to him in Italian). They seem to have an alcohol licence - so perfect for an early evening spritz, or a late evening caffé correto.
The downside is that this is a self-service joint. While everything is stylishly done, all eating implements are disposable. So never mind the side plate.
