I've gone to WDW solo lots of times, so I've eaten at plenty of resturaunts solo. LeCellier at lunchtime was good because I could sit by the window and watch everyone walk by. Fun for people watching! Personally, I had a bad experience with the communal dining at Teppen Edo. I was seated next to a teenaged girl, who obviously had encountered her worst nightmare-being seated next to a middle-aged stranger (and she acted like she could just TELL I was a dreaded math teacher, besides!) And unfortunately, it was too loud in there to carry on a conversation with anyone but your nearest neighbor. One tip-wherever you go, be sure to tell them you're alone and would like something to look at during your meal since you won't have anyone to talk with. I've gotten some real nice views that way-tankside at Coral Reef, window tables, and generally, my servers have gone out of their way to make me feel comfortable. And don't discount character meals, especially at the "convention-type" hotels, like Cape May Cafe, where you won't be the only solo there. It really makes the time go by to watch the kids interacting with the characters, and unless you bear a striking resembalance to Minnie or Goofy, no one's going to pay any attention to you except the servers.
