A mobile galley cart, comprising:
- a wheeled insulated housing formed from opposing sidewalls, opposing end walls, a top and a bottom, with one of the opposing end walls being a door configured to open to access an interior of the housing;
- a thermoelectric chiller mounted near the bottom of the cart;
- cold air ducting in at least one of the sidewalls, end walls and bottom in fluid communication with the thermoelectric chiller, the cold air ducting opening to the interior of the mobile galley cart through a plurality of openings through at least one of the sidewalls and end walls;
- warm air ducting including a warm air exhaust arranged to exhaust warm air from the mobile galley cart;
- and
- wheel brakes actuated by handles located at both end walls of the mobile galley cart, each of the handles operating independently of the other to allow the wheel brakes to be disengaged from either end of the cart,
- wherein the handles are interconnected to the wheel brakes through cabling, and wherein the handles are rotated downward to pull the cabling to disengage the wheel brakes, and wherein releasing the handles causes the handles to rotate upward to release tension on the cabling and engage the wheel brakes.
