The consortium that was last week awarded the contract to deliver the East West Link has shown its appreciation by shouting a select group of public servants dinner at Melbourne's most expensive restaurant.

The East West Connect consortium, led by development giant Lend Lease, celebrated winning the $5.3 billion contract by hosting a lavish dinner at top restaurant Vue de Monde. The dinner was attended by senior staff from the Linking Melbourne Authority, which has overseen the Napthine government's flagship project since its inception in 2011.

"East West Connect hosted and paid for a project dinner last night which was attended by executives from all lead consortium members and LMA," an authority spokeswoman told Fairfax Media.

It is understood the dinner was attended by Linking Melbourne Authority chief Ken Mathers and Lend Lease chief Dave Saxelby, among others.
