Food Allergy Counseling: Custom Chef Cards

A recent food allergy coaching client of mine showed me the chef card she created for her son, who is allergic to dairy and sesame. 

She gets compliments on it all the time from chefs. They love it. And I can see why. Courteous, clear and direct; it opens doors and opens up conversation.

How are you communicating with restaurants about you or your loved one with food allergies about your needs and dietary restrictions?
