First of all, you are talking about restaurants, which should refer to small and medium-sized mass consumption. In addition, 100 table has two or three boxes, and each meal can accommodate 100 people. Tableware and tables and chairs are not very expensive. Relatively speaking, air-conditioned TV kitchenware is much more expensive than it. As for the price, your question is not very detailed, so I can't tell you. I don't know what grade and quality you want ... I suggest writing a list.
