This is a WDW restaurant board, however I know DL better anyway
Have you considered Cafe Orleans? It used to be cafeteria-style, but now it is table service. Sitting outside is wonderful! You can peoplewatch, and yet it is so calm!
What they serve? The Monte Cristo (regular one, and one with just cheese), they have a crab sandwich, crepes filled with seafood (and I think they also had it filled with something else). There were some salads on the menu (I think one with shrimp). As dessert, we had the Mickey beignets. There was also a crepe filled with chocolat and something.
It has been more than a year ago, so I don't remember everything. If you click on the dining review link of the 2006 DL-trip in my signature, you can see some pictures.
River Belle Terrace, while cafeteria-style, is also very nice! Did you know Walt used to have breakfast there on Sundays? Mickey pancakes first thing in the morning while you watch the Mark Twain go by for its morning run is just an amazing way to start the day!
I have never been there but I heard that Storyteller's Cafe at the Grand Californian is also very nice.
