Dang food means that it can only be consumed inside the establishment and cannot be taken away or taken out. And the meals inside are usually mostly specials and discounted dishes with low profit prices, which is why there is such a rule that you can't take away.

The name "dangshi" (堂食) originated from the meals prepared for the prime minister during the Tang Dynasty. From Li Zhao, Tang Dynasty, "Supplement to the History of the Tang Dynasty," Volume 2: "After each meeting of the dynasty, the prime ministers and bureaucrats would eat in the hall." Translation: After every court meeting, all civil and military officials would eat together. In modern times, it means that the food can only be consumed in the store, and cannot be taken away or sold out. The ban on eating in the hall is the opposite meaning that it can only be packed or taken away.
