A dining car for a railway vehicle, including a first side face and a second side face laid out facing each other, and a first lower floor, the dining car comprising a first consumption area which is an area in which passengers are placed for eating, a second preparation area which is a service area in which onboard personnel prepare meals, and a third technical area which includes technical equipment for operating the dining car, wherein:

• the first side face includes first supporting portions extending from the first side face at a first height for supporting a second upper floor, and
• the first, second and third areas are all on the first lower floor
• wherein the dining car includes the second upper floor, borne by the first supporting portions,
• wherein the second upper floor extends transversely between a first side edge of the second upper floor at a second height and a second side edge of the second upper floor, the second height being greater than the first height relative to the first lower floor, the first side edge extending from a distal portion of the supporting portions relative to the first side face, the second side edge being spaced apart from the second side face by a non-zero distance, so as to form a transverse aperture between the second side edge and the second side face,
• wherein the second upper floor forms a mezzanine extending above the first lower floor, so that the transverse aperture looks down on the first lower floor, and
• and a vertical longitudinal plane cutting the transverse aperture also cuts one of the first, second or third areas.

A railway vehicle, comprising at least one dining car, the dining car comprising:

• a first side face and a second side face laid out facing each other, and a first lower floor, the dining car also comprising a first consumption area which is an area in which passengers are placed for eating, a second preparation area which is a service area in which onboard personnel prepare meals, and a third technical area which includes technical equipment for operating the dining car, the technical equipment comprising a cooling unit for preserving beverages and an electric supply unit, wherein:
• the first side face includes first supporting portions extending from the first side face at a first height that support a second upper floor, and
• the first, second and third areas are all on the first lower floor, and
• wherein the dining car includes the second upper floor, borne by the first supporting portions,
• wherein the second upper floor extends transversely between a first side edge of the second upper floor at a second height and a second side edge of the second upper floor, the second height being greater than the first height relative to the first lower floor, the first side edge extending from a distal portion of the supporting portions relative to the first side face, the second side edge being spaced apart from the second side face by a non-zero distance, so as to form a transverse aperture between the second side edge and the second side face,
• wherein the second upper floor forms a mezzanine extending above the first lower floor, so that the transverse aperture looks down on the first lower floor, and
• wherein a vertical longitudinal plane cutting the transverse aperture also cuts one of the first, second or third areas.
