Iron Man 2 is one of the few who will dare multiple unexpected references to Belgium.

First at 1h10.11:

HAMMER: This is the FN-2000, from Belgium. They do make something better than waffles. It’s beautiful, but I can tell this isn’t disco enough for you, so I’m gonna put it right here.

Later at 1h21.45 (found by Thomas):

STARCK: Jarvis, could you kindly Vac-U-Form a digital wire frame? I need a manipulable projection
JARVIS: 1974 Stark Expo model scan complete, sir
STARCK: How many buildings are there?
JARVIS: Am I to include the Belgian waffle stands?
STARCK: That was rhetorical. Just show me.
