The 300 star part owns Hollywood's Korean eaterie Shin BBQ, along with several other proprietors, including Danny and Chris Masterson.

Two ex-employees, who worked as a cook and a dishwasher, filed legal papers at Los Angeles County Superior Court on Tuesday (16Aug11), claiming the owners, including Butler, failed to give them wages, rest time and meal breaks they were allegedly owed.

They are requesting that the restaurant owners are forced to open their payroll books, as well as hand them back pay and other damages, reports TMZ.com.
