Chopstix (1979)

This Catering Service Delivers Their Goods with a Personal Touch! When a young woman inherits a grand mansion from an unknown benefactor, she also inherits a $25,000 debt in overdue taxes. With nothing but a beat-up old catering truck to her name, she turns to her aunt, who manages the city's most exclusive brothel, to borrow some girls. Offering a tempting menu of both gourmet dishes and carnal delights, she earns enough to settle the taxes before the estate's shady lawyer can steal it all. She marks her victory with a wild, over-the-top orgy at her new restaurant, "Chopstix Manor."
