 In all three groups, though, every restaurant has the typical look of a French "brasserie" with wood panelling and wall mirrors, closely spaced tables, and bench seating in red upholstery.All the servers are women, dressed in black uniforms with white or yellow aprons, and no male staff are visible.And the restaurants do not take advance bookings, which at most of the European locations means that patrons must queue on the pavement outside for half an hour or more before they can be seated.
