We print our chef card on wausau AstroBright in TerraGreen. It is a visible chef card. I really like Adrienne's system--I like the placement on the order--a good precaution and the Table #___.
We have encouraged the restaurant to keep it if they have never seen a chef card before to help train new employees. We keep a stash in our pack with 2 epis, benadryl, inhalers, allergist letter. We keep a stash in the car glovebox for road trips.
