Grand yet relaxed – as only restaurants in Belgravia can be – “high-class” Santini is the go-to haunt for old money in the neighbourhood, and with more than 30 years of trading under its belt, the old girl is still looking remarkably good for her age. The huge outside terrace is a lovely place to sit on a warm summer’s evening, although the chic, flatteringly lit interior has plenty to recommend it too. Venetian flavours dominate the high-end menu, from carpaccios and smart salads to homemade pappardelle with rich artichoke sauce or char-grilled veal chop with wild mushrooms and rosemary. Everything is executed as it should be and there’s an almost exclusively French/Italian wine list to accompany. Santini’s proudest claim to fame is that it was Frank Sinatra’s favourite restaurant in London, and we feel that he’d still approve of its “impeccable” food and service.
