Last week the city where I live hosted a "Dîner en blanc" (White Dinner) in one of our main streets.
The "Dîner en blanc" was invented in Paris by François Pasquier about 25 years ago and has been held in numerous cities around the world since then (eg. New York City, Sydney, Nairobi, Barcelona,..).
On the original homepage it is stated that the "Dîner en blanc is simply a friendly gathering whose sole purpose is to create a magical evening".
Of course the event that was hosted in my city didn't reach the size equal to the Parisian one but it was still a great opportunity to get together and to enjoy a picnic in style.
Let me know if you've experienced a "Dîner in blanc" before and where!
