This is the restaurant at the bottom of No. 11 Cadogan Gardens Hotel. 'Tartufo' translates from Italian meaning Truffle, hence the extensive use of truffle in their menu. The menu really did taste as good as it sounded. I had the Winter Truffle Tortellini with Walnut, Mascarpone and Olive Oil which was very rich but the perfect amount for a starter. Then I had some yummy venison, cooked to perfection and we couldn't resist sharing a Chocolate Crunch pudding with the perfect accompaniment of lemon ice cream. Service was very good and the atmosphere was relaxed but relatively smart. Definitely worth visiting for a treat - such as Valentines Day next week!
