Cheerful Fish Thug is a fast food restaurant chain based on Riesel, but it also has a minor presence on a few other worlds. Seafood is the primary focus. According to several critics, the menu has a "tragic lack" of options for Human consumption, featuring several types of fish that are outright poisonous to Humans.
The restaurant is notorious for instructing its servers to behave like typical mafia thugs, which has led to both amusement and outrage amongst customers. Regardless, it receives plenty of business.
