Service at The Markham is faultless. Or perhaps waitress service everywhere is zippier when you're having dinner with David Gandy - a man paid to look melancholic in underpants for Dolce & Gabbana. We gossip about Top Gear, Clarkson, David's collection of sports cars, my seven failed driving tests and David's wish that I never attempt an eighth. Hurtful. Honestly, you give one BSM instructor a nervous breakdown and you never hear the end of it. Steak frites arrived: sturdy, non-negotiable portions served on wooden boards. Seared tuna appeared on a bed of not-so-great chopped green tomato salsa. Its more challenging mystery ingredients I might have got to the bottom of had I not been distracted by a six-foot, size-zero Russian 18-year-old, in a barely there skirt and stockings, who had table-hopped to kiss a boy, which caused merry passive-aggressive hell with his girlfriend.
