The blog, Online Marketing for Restaurants has started to build out a list of restaurants using Twitter. Some use it to promote deals. Others for customers service. Bottom line is that if you’re in the restaurant business you should be following each and every one of these guys. Doesn’t matter if you have your own small pizza joint and want to do some Twitter marketing or you manage marketing for a billion-dollar franchise, Twitter helps to even the playing field, gets you closer to your customers, helps you build relationships and can ultimately help drive business.
