George Calombaris's original Hellenic Republic will re-open next month as an American barbecue joint after deals were struck to salvage three restaurants from his collapsed culinary empire.

The KordaMentha team handling the liquidation of the Made Establishment business part-owned by Calombaris completed sales on Wednesday for three of its suburban restaurants, the original Hellenic Republic in Brunswick East, the recently renamed Vita Ristorante in Kew and Hellenic Republic in Brighton.

No buyers have been found for Made's flagship Elektra restaurant in Melbourne, Hotel Argentina in Williamtown or his string of seven Jimmy Grants souvlaki shops, which abruptly ceased trading last Monday when the cash-stricken business was put into voluntary administration.

The change of ownership of the Brunswick East restaurant, which was late last year rebranded as Crofter Dining Room & Bar, means a dramatic change of menu for the Lygon Street eatery, which under chef Matt Wilkinson had embraced a meat minimalist diet.
