国内在线订餐网站的兴起并非来源于国外,食色性也，“吃”是人们的最根本要求，也是每个人都避不开的话题。现在随着物价的飞涨和生活节奏的加快，都市白领想要在高楼林立中安稳的吃上一顿实惠便捷的午餐变得越来越难,越来越多的上班族中午会点外卖,由此产生了巨大的外卖需求.有关数据显示，在长沙市城区90％以上的餐馆都提供送餐服务，营业额一般要占总营业额的10%左右。在商贸集中区域，外卖营业额占总营业额的３0%。随着人们生活节奏的加快和生活习惯的改变，外卖营业额还将继续攀升,外卖市场的潜力是巨大的。而随着互联网的高速发展，越来越多的传统企业开始试水电子商务。日前，连锁巨头麦当劳在继肯德基、必胜客之后开通网上订餐业务，与此同时，以爱送餐网为代表的一大批网上订餐平台也如雨后春笋般应运而生.据爱送餐网提供的数据显示，今年，全国新开通的第三方外卖订餐网站已超过５0家，仅北京地区就已存在１0家左右。和ＬivingSociａl即时服务频道相似,国内外卖订餐网站不仅提供了餐馆的详细菜单等信息,还拥有丰富的商家资源,给用户提供了更多的选择。爱送餐（www.aisoｎgｃaｎ．com）是国内领先的外卖订餐网站之一,总部在湖南长沙，致力于为中国广大消费者提供最优质的、最便捷的网上外卖订餐服务,打造中国网上外卖订餐第一品牌,为用户提供精准的小半径点餐服务，解决城市白领、大学生群体、宅男宅女们的吃饭问题。爱送餐提供海量外卖菜单随你挑选,您只需轻点鼠标,就能享受送上门来的美味佳肴香哈网(http:／／wwｗ.xiaｎgha。coｍ）是一个免费的外卖订餐平台，涵盖了中餐、西餐、糕点等各种类型的餐馆，为用户提供周边餐馆的详细信息。海量菜单随心挑选,仅需一个电话，美食到身边，足不出户，也能享尽美味佳肴！目前，香哈网上的餐馆信息已覆盖了北京市大多数的区域。美餐网（htｔｐ：/／meicaｎ。com)主打“附近的外卖详细菜单”，目前已经收集了北京的上千家餐厅的几十万道外卖美食。用户登陆美餐网之后,会进入一个“餐厅地图”的页面,然后把自己喜欢的餐厅放到网站的首页，定制一个属于自己的外卖订餐页面，最后通过美餐网直接在线订餐。综上所述，加之我们所关注的是针对各高校学生的订餐系统,我们服务的对象是高校学生，我们认为网上点餐系统的前景还是非常光明的，伴随着移动通信终端的迅速发展网上点餐系统将会更加丰富人们的生活，满足人们的需要。
