CGP, why are you going on the Applebee's website?? Are you an Applebee's addict?? I've never been on the Applebee's website, so I wouldn't know how it was setup originally to consider the way it is setup now as weird :)
I think this is a way of welcome its viewers to their restaurants. Since this site is used to advertise the restaurants chains, the 'see you tomorrow' is just a way to inform you that you can join them in the restaurants when you are available.
