One of the restaurants, Heathcote's flagship Simply Heathcotes in Liverpool, had been open for 10 years.
Both Simply Heathcotes and The Olive Press in Leeds closed last week, the Olive Press with 17 redundancies.
Heathcote has also reportedly blamed the closure of the restaurant on the demolition of a nearby bridge link, which significantly reduced footfall to the area.
Commenting on the closure of his Olive Press site in Leeds, a spokeswoman said the site had simply suffered from a fall in footfall post recession, and the "tough decision" had been taken to close it.
Speaking to a local newspaper, the company denied being in any financial difficulty.
Heathcote Restaurants now operates The Longridge Restaurant, near Ribble Valley, London Road Restaurant & Wine Bar in Alderley Edge and Grado Restaurant & Tapas bar in central Manchester.
The Olive Press, its six strong Italian restaurant chain, now includes sites in Clitheroe, Cheadle Hulme, Bolton, Liverpool, Manchester and Preston.
