Sleek as the Eurostar and buzzy as a French railway station, Caboose is named for the carriage where guards bide their time between stops. Sited beneath the lowering bulk of the Westin Hotel, the austere interior, warmed by raw timber, is a welcoming space that protrudes into City Square. Whistle-stop coffee service is available in the stand-up service area, or if you’re aboard for the long haul, stow your luggage and kick back with a brew of Coffee Supreme’s Fairtrade organic blend while you peruse the Mediterranean-influenced menu. Grab a quick ristretto with aromas of cedar and licorice and a short, sweet aftertaste, or settle in with a caffe latte redolent of milk chocolate and warm cinnamon. Switched on but unobtrusive staff are more efficient than the Paris metro.
