Dinner points, often abbreviated DP, are a $6.25 meal equivalency at the Snack Bar for students on board plans that allow them who don't eat dinner at a dining hall. They must be redeemed the same night that dinner is missed. They are often the deciding factor for students who are deliberating whether to dine out or visit the Snack Bar late at night (after the dining halls have closed).
