共享经济如火如荼共享餐厅是什么，共享单车，共享雨伞，共享充电器，现在又出来一个共享餐厅。

什么是“共享餐厅”？消费者通过APP订购附近（同一建筑或800m内）餐饮单位制作的餐食共享餐厅是什么，餐厅提供就餐场所，并自备餐具到制作餐食的餐饮单位取餐。

本程序模拟共享餐厅就餐业务。程序的运行结果如下所示：

为两者提供的服务主要有：（1）为消费者：开台，点餐，就餐，结算；（2）为餐饮制作单位：取餐，菜单管理，注册，注销。

主要的业务流程如下：共享餐厅准备基础数据，用户开台，用户点餐，餐饮单位制作食物，工作人员取餐，用户用餐，结算，关台。

在这个业务中，设计到了类图如下：

各个类图详情描述如下：
