The system relies on two substantially horizontally disposed latch levers to secure the galley door which in turn restrains a galley cart in position within the galley. The ends of the latch levers are received in a recess formed in the door to secure the door. Raising the latch lever releases the door and positively pushes the door outwardly. The latching configuration allows the doors to be slammed shut without the need to further manipulate the latch levers. ## Claims ### Claim 1 A latch for latching and unlatching a door of a galley
