What is the text mainly about?

参考解析：

主旨大意题。根据第一段第二句“According to statistics from Technomic, 86% of consumers are using off-premise channels at least once a month, and a third of consumers are using it more than they did a year ago.”可知，根据Technomic的统计数据，86%的消费者每月至少使用一次非经营场所渠道，三分之一的消费者比一年前更频繁地使用这种渠道。再根据第二段第一句“Most restaurants companies are chasing these trends simply to keep up with quickly changing consumer demands.”可知，大多数餐饮公司追逐这些趋势，只是为了跟上快速变化的消费者需求。由此可退出，这篇文章讲述的是外卖对餐厅来说有多重要。故选D。
