Honestly, for me, DLR is about food experiences rather than a couple singular TS restaurants. I have a list of favorite snack and food items that I like to have on trips, and that is my focus rather than picking singular restaurants, which I am more likely to do for a WDW visit. I think you have to approach DLR differently. Since it's a big locals park, a lot of great food items aren't limited to TS meals, which locals are less likely to indulge in. Some of my favorites are Mickey macarons (the raspberry is THE best) and Matterhorn macaroons from Jolly Holiday, a chimichanga, a corn dog from the Little Red Wagon, a apple slushy (available in multiple places), churros, Mickey head sourdough bread, and that's just a start.
If I was picking TS, I would choose Carnation Cafe in DL (took family who are WDW regulars there recently on their first visit, and it was very well-received) and Storytellers at DCA because it is in the Grand Californian (also well received by same family) and even though that's outside the park, it's super close and counts for us.
