33 Dover St, London W1S 4NF
The Dover is a Mayfair restaurant by Martin Kuczmarski, former right-hand man to Soho House's Nick Jones, aiming for understated glamour with NYC Italian-inspired cuisine. With an ambience best described as "casual but not too casual", there's a real feel of old-school Mayfair hospitality here. The menu is also welcomingly old-school with dishes including an excellent Chicken Cordon Bleu. On top of that, there's an impressive bar specializing in martinis that' it's worth visiting for alone.
