Fry night light

Here is a print ad from Canada for McDonald's:

Too bad this is only a print ad, it would make an amazing piece of direct.

Fry lights

Here is an ambient billboard for McDonalds:

Skylights that were visible up to three miles away were used to illustrate that McDonald's has the Best Fries on the Planet.

Interactive ice sculpture promotion

Here is an ambient ad from Canada for McDonald's "Cool off with $1 Drinks" promotion:

$4,000 worth of Canadian dollars, or "loonies" as the Canadians like to call them, were encased in sheets of ice and shaped into the iconic McDonald golden arches.  People chipped away at the seven foot tall ice sculpture for the icy coins. 

The happiest box of all

Here's a commercial from the UK for McDonald's:

Larger-than-life McDonald's happy meal boxes were set up in several locations.  From shooting jets of water to mechanical robo-happy meals, each replica of the McDonald's kid's meal had a fun little surprise. 

McDonald's fresh vegetable salad

To illustrate how fresh their new vegetable salad is at McDonald's in Israel they created this paper placemat:

It was made to resemble a wooden cutting board with knife marks.  The copy roughly translates to "Cut on the Spot, Only Upon Ordering"

What is the conversion rate for Monopoly money?

This is a fun promotion for McDonald's Monopoly game in Vancouver:

There are some nice touches in this promotion including a sidewalk decal that looks like the Monopoly GO square, and the Monopoly money tunnel.  Since chances are most people do not walk around town with Monopoly money in their pockets.  

The explainer doesn't say what the conversion rate was for Monopoly money to get the free fries.  I am kind of curious since it looked like cashiers were giving away Monopoly money as "change."  But if customers are already in McDonalds, spending fake money for free fries, the odds they'll spend real money on a burger or drink to go with their fries is pretty good.
