I am not sure if this place is open 24 hours but I know it is open very late for a fact because the one time I went over around 3am hungry and in the mood for burgers, sure enough they were open. Just like any other In N Out, this one had the same menu and prices but the quality was pretty good in comparison to the other fast food places nearby, including the Subway in the same area which was mediocre. The place had wonderful workers who brought out the food not too long after I ordered, which is generally the major concern when eating at a fast food restaurant.
