Snail steaks were a Ferengi delicacy. When Nilva visited Deep Space 9 to talk about Grand Nagus Zek's future and females wearing clothes in 2374, Zek suggested they discuss the matter over snail steaks. While Nilva relished the thought of snail steaks, he decided to dine with "Lumba" (Quark in disguise) instead. The two of them ate at Quark's. (DS9: "Profit and Lace")
