I think DLR, and especially DL, has several very good QS options.
- Plaza Inn - the Fried Chicken is the most popular dish and it is really yummy.
- French Market - lots of good options including the salads and chicken.
- Redd Rocket's Pizza Port - the salads are pretty good; I like the Asian Chicken Salad.
- Jolly Holiday - good salads and sandwiches. I especially like the Tomato Basil soup and there are lots of yummy desserts.
- Earl of Sandwich - good sandwiches (especially the holiday special).
While not really a counter service (closer to a Table Service, but no reservations), the Carthay Circle Lounge is outstanding.
