Brown Derby is the only place in DHS where I feel like I'm actually getting a decent meal. Mama Melrose and Prime Time have food, if not the best food. Everywhere else, I basically turn my nose up at.
...Starring Rolls is probably the best of the CS, though. Sci-fi might be doable if you stick to burgers, but I've found their burgers dry and pretty tasteless no matter how you order them done.
