The smart bar at Christopher's (once London's first licensed casino) is a safe bet for a decent Martini in theatreland. The stage is set with a seductive backdrop of muted masculine tones, gleaming metallic fittings and lighting that makes everyone look A-list. Perch at the sleek onyx sharing table or settle into a moss-green banquette to review the stars of the show: a selection of classic, contemporary and decadent Martinis, all properly made with your gin or vodka of choice. We're rather fond of the namesake Christopher's, made with Snow Leopard vodka, Lillet Blanc, Domaine de Canton ginger liqueur and plum bitters. The bar team here knows its stuff and US classics such as Manhattan, Bronx, Brooklyn and Sazerac are perfect with a menu of stateside staples (sliders, tacos, Cobb salad, Philly steak sandwiches).
