"Take Elevators" is an objective in the quest The Hunger Pangs in The Horrible Hunger of the Ravenous Wattle Gobbler DLC
Head into the oven where the food came from. Go into any of the elevators arrayed against the Southern Wall. Go up to one of them and use it. This will bring you up from the kitchens to the Grove of the Gobbler. You will be held in the elevator a minute or two by a force field. Once it drops then you have a few new concerns.
