At DL, we like to do French Market. The food is good with a Cajun flavor. But really, we got there simply to have benigets (pastries) afterwards. They're not as good as the Jazz Kitchen, but the get the job done. That really the only CS at DL that I can say we need to do. All the other one are sorta ho-hum. Especially after they killed the Fried Green Tomato Sandwich at Hungry Bear.
As DCA, hands down my favorite is Pacific Wharf. I always get Clam Chowder in bread bowl. They bread is baked fresh daily and is awesome. And if you don't like clam chowder, they always have a great soup of the day instead. I can't imagine a trip to DL without going here. The Lucky Fortune Cookery has good Chinese food. Cocina Cucamonga ain't "Central Valley" quality Mexican, but it's still better than anything you'd get east of California. Flo's is good food with awesome ambiance. And we even like Smokejumpers for the chili burger. Overall, for us, DCA kicks DL's hinders when it comes to quick service.
