The Sha-Boom Ka-Boom! Cafe is a restaurant in Springfield. John once took the Simpsons (everyone but Homer) to this restaurant. As evidenced by its design, name of its foods, and memorabilia, the theme of the Sha-Boom Ka-Boom! Cafe is based on nuclear deterrence and nuclear weapons. It recently appeared in The Simpsons: Tapped Out during the Secret Agent 2017 event as a premium building that costs 70 donuts.
