New Adventures of Zak McKracken -- cheese chest ???

[AryYrk]

I finished this a few months ago ... as far as I remember without any serious problem.  Now I'm playing it again but I'm completely stuck near the end.

I've got to Snuckey's Pizzeria in Rome ... VERY near the end of the game and can't do anything there.
I'm desperate ... I looked up the walkthrough and it says to give Luigi the cheese chest --- but I haven't GOT a cheese chest or any cheese.

PLEASE  HHEELLPP !!!!
Where was I supposed to find the cheese or cheese chest?

Whoa !
Nobody played this game? ... it's a good one!

Did it ... and finished the game!
