Do you have especially fond memories of your 9th birthday party under the golden arches? Then McDonald's Hong Kong has the wedding package of your dreams! Plus, a Happy Meal can make a wonderful keepsake for your guests.
It's worth pointing out that in many other countries, McDonalds is a fancy American restaurant that you dress up to go to. I don't know about the particular restaurant in Hong Kong, but there isn't the same thought process about McDonalds in other countries. It's more expensive, they have fancy waiters and tablecloths, etc.
