After working at "Mr. Chow" in New York for 25 years, Chau opened his own restaurant, "Phillipe Chow." Chow alleges that Chau is duping customers into thinking "Phillipe Chow" is associated with "Mr. Chow."
The Chow-Chau war includes allegations of spying, phony reservations, prank phone calls, vandalism and threats, TMZ reported.
The first "Mr. Chow" opened in London on Feb. 14, 1968.
