TECOMA residents who have taken their fight against McDonald's to Chicago inflated 30 kangaroos in a colourful protest outside one of the fast food chain's US outlets.

Protest organiser Garry Muratore said he and three other delegates from the Burger Off movement distributed the toy marsupials carrying signs saying "I voted 'no' to McDonald's in Tecoma" outside the Rock 'n' Roll McDonald's in downtown Chicago.

The Melbourne activists, who are campaigning against the construction of a McDonald's restaurant in the Dandenong Ranges community, have attracted widespread media attention in the US.

"It's just surreal. We placed an ad last Thursday and the American media's gone gangbusters," Mr Muratore said.

"The media see it as a David and Goliath story."

He said the small Aussie contingent handed out leaflets explaining their battle to passers-by.

"They're amazed that a town has said 'no' and McDonald's has continued to do this," he said.

Tomorrow the campaigners will deliver the results of an online petition signed by almost 100,000 people to McDonalds' Chicago headquarters.

Mr Muratore said they were writing an email to a McDonald's representative, asking for someone to be sent to receive the petition at the building.
