Taxi stands are located at all major Manhattan transportation terminals, including Penn Station, Grand Central Terminal and the Port Authority Bus Terminal. When hailing a cab on a street, simply stand on a corner, close enough to the curb to be seen by oncoming drivers, and raise your hand. Once inside, give the driver the address of your destination and try to include the nearest intersection.
