Scott Melton, founder of the defunct Sushi Nights in Deep Ellum and one of the driving forces behind Deep Sushi before he was a casualty of a partnership rift, has ripped a page from Kim Il Jong's playbook and gone nuclear. Melton is general manager of Atomic Sushi Grill, a Japanese-Chinese hybrid that bubbled up from the defunct Johnny Rockets in the West End. Atomic symbols indicate spiciness on the menu. Chinese fare is labeled "China syndrome." Restrooms are indicated with fallout shelter signage, a disturbingly accurate bit of labeling when you think about it.
