Little Chef has been trialling a menu at its Popham outlet that contains dishes such as braised ox cheeks and coq au vin, created by Blumenthal, owner of The Fat Duck restaurant.
Blumenthal's attempt to turn the Little Chef around was featured in a Channel 4 documentary that aired earlier this year.
The menu has proved popular and plans have been made to introduce the dishes at all 175 Little Chef restaurants.
Little Chef was saved from bankruptcy in 2007 after private equity firm RCapital stepped in to save the chain.
The chain was founded in 1958 as an 11-seater snack bar in Reading, and has had a series of owners since that time including Granada, private-equity firm Permira and Travelodge.
Little Chef was unavailable for comment this morning.
