Best restaurants for solo dining?
No such thing.
Feeling comfortable dining solo is not a function of the restaurant, it's a function of the diner. If you can feel comfortable dining solo at McDonalds, you can feel comfortable dining solo at any WDW restaurant.
Forget about trying to find a place that is "better for solos", and instead concentrate on finding places that
you want to eat. Look at the menus on AllEarsNet, look at reviews on the DIS boards, check out the various themes, and decide where to eat based on what appeals to you.
The big advantage of going to WDW solo is being able to do anything you want without worrying about the needs of traveling companions. Solo means complete freedom to eat in any restaurant, stay at any hotel, or experience any attraction, any time you want - or skip any of them. DH always drag you to Planet Hollywood, but you don't like it? Skip it! Kids always drag you to CP, but you don't care for it? Skip it! Always wanted to try Rainforest Cafe or California Grill but DH and the kids didn't want to? Go for it!
Ride RNRC 5 times in a row, eat a Mickey Bar for breakfast, have a glass of wine at Rose and Crown and read a book, or take a whole day just to go shopping at the outlets - who cares? You're on your own time, nobody elses.
Not sure where to start? Go through the menus and pick your 5 favorite meals (mix up some breakfasts, lunches, and dinners), and make ADRs there. Pick a few appealing counter-service meals, too, and make note with your planning materials so you can try them along the way. Once you get that far, the rest of your trip will fall into place like Tetris blocks and you'll have the time of your life.
