The movie begins with Ricky (Timmy Hung) as an incompetent chef at a restaurant owned by the harsh manager One-Eye Dragon (Law Ka-ying).

That night, Ricky receives a phone call from his older brother Mike (Wayne Lai), who knows about the inheritance money and wants to use it for his idea.

Ricky travels to Osaka, Japan to find his equally incompetent brother Mike, who is trying to escape from his own apartment because someone who he owes money is banging at his door.

It turns out Mike has a vision for a Chinese restaurant combined with live Osaka Pro Wrestling in Hong Kong.

They hold a recruiting session for performers, which attracts all kinds of weird people including a fire-breathing Bruce Lee look-alike, a drunken kung fu master, a Classical Chinese dynasty warrior, a sumo wrestler, and a transgender football player.

The restaurant gains a reputation and attracts the attention of elderly food critic Chau (Sammo Hung), who makes a reservation one week ahead.

Though she is at first reluctant to leave the restaurant, she accidentally sees Ricky without his mask on and realizes he is not Super Delfin, but the man who pushed her into the river.

Encouraged, Mike returns to work and plans to serve Chau a secret, ancient recipe for xiao long bao found along their father's inheritance money.

The restaurant is brought back to fame and all the employees are too busy making more xiao long bao to put on a wrestling show, having revitalized elderly customers fight in their place.

Some time later, the crew of the Osaka Wrestling restaurant is seen in Japan, where they have a successful food stall and even serve the real Super Delfin.
