Originally, Sheldon objected to eating, since at the time, they ate at Big Boy on Tuesdays. He enjoyed his hamburger from The Cheesecake Factory so much that he changed the schedule for them to eat at the Cheesecake Factory every Tuesday. The reason for this was the Cheescake Factory cheeseburger was a single decker burger, while Big Boy produced a double decker, according to Sheldon, this gives a "much more satisfying meat-to-bun-to-condiment ratio". There is an Olive Garden down the street.
