Galley container for an aircraft, comprising - a first shell having a peripheral rim defining an opening for access to an interior of the galley container; - a second shell within the first shell, having a further peripheral rim, the second shell being formed of a material of high thermal conductivity, wherein the second shell encloses the interior of the galley container; wherein each shell comprises a roof element (8, 22), a floor element (10, 24) and at least two sidewalls (9, 23), the galley container further comprising: - a thermally insulating layer (26, 30), thermally insulating the second shell from an exterior of the galley container; - a receiving portion located above the roof element of the second shell for receiving a cooling element or a coolant, which receiving portion is provided within the first shell and is thermally insulated from the exterior of the galley container and partially thermally insulated from the second shell, - a separating wall arranged between the receiving portion and the roof element of the second shell; - a heat transfer device (52, 55, 36), extending along the roof element of the second shell, and from the roof element towards the floor element of the second shell along the interior of the galley container over at least a surface of the sidewalls of the second shell, such that heat from the interior of the galley container is transferrable by thermal conduction, via the sidewalls and the heat transfer device, to the receiving portion; and - at least one door provided at the opening to close the galley container in a closed position of the door; characterized in that the separating wall forms an insulating layer that thermally insulates the roof element over its entire surface, the wall being hermetic so as to prevent passage of air between the interior of the second shell and the receiving portion, and so that heat transfer from the interior to the receiving portion takes place primarily by the thermal conduction via the sidewalls. - a first shell having a peripheral rim defining an opening for access to an interior of the galley container; - a second shell within the first shell, having a further peripheral rim, the second shell being formed of a material of high thermal conductivity, wherein the second shell encloses the interior of the galley container; - a thermally insulating layer (26, 30), thermally insulating the second shell from an exterior of the galley container; - a receiving portion located above the roof element of the second shell for receiving a cooling element or a coolant, which receiving portion is provided within the first shell and is thermally insulated from the exterior of the galley container and partially thermally insulated from the second shell, - a separating wall arranged between the receiving portion and the roof element of the second shell; - a heat transfer device (52, 55, 36), extending along the roof element of the second shell, and from the roof element towards the floor element of the second shell along the interior of the galley container over at least a surface of the sidewalls of the second shell, such that heat from the interior of the galley container is transferrable by thermal conduction, via the sidewalls and the heat transfer device, to the receiving portion; and - at least one door provided at the opening to close the galley container in a closed position of the door;
