Yeah, i got that list from their website.

(ignore the javascript alert). it looks like they have a vegan meal that is
totally non-dairy, but i wish that they had a non-dairy meal.
here is something that really annoys me, they have a non-lactose meal that
is meant for milk allergies too, but one of the allowed foods is non-dairy
creamer?!?! I think they need a little education. if anyone is a little
more eloquent than i, it would be great if someone would send them a letter
(hint hint- mark??)

    Non-Lactose Meals
    Non-lactose meals are available for customers who are diagnosed as lactose
    intolerant or for those who have allergies to the proteins in milk. Lactose
    intolerance is a condition where the body does not produce enough of the
    enzyme lactate.

    The lactose-free diet is designed to prevent or reduce bloating,
cramping, and
    diarrhea associated with ingesting lactose-containing products. This diet
    involves avoiding milk and dairy products such as butter, cheese,
cream, and
    yogurt. Milk products like casein, whey, skimmed milk and non-fat milk
    solids, curds, and sodium caseinates should also be avoided.

    Lactose is often used as a filler in artificial sweeteners, cold cuts,
hot dogs,
    stock cubes, dried soups, dry cereals, and processed foods. Labels on all
    processed foods should be checked for the presence of milk and milk
    derivatives. Lactate, lactalbumin, lactylate and calcium compounds, and
salts
    of lactic acid do not contain lactose.

    Prohibited
    Cheese and Dairy Products, Yogurt, Butter, Manufactured Meat Products,
    Cakes and Biscuits, Sauces, Batters, Sweets and Puddings, Instant Potato
    Mix, Toffee/Fudge/Chocolate, Caramels, Cream Soups

    Allowed
    Fresh Meat, Fresh Fruits and Vegetables, Non-Dairy Creamer, Poultry, Fresh
    Fish, Eggs, Soy Milk, Sugars and Preserves, Salt and Pepper, Potatoes,
Rice,
    Pasta, Bread, Kosher, Nuts, Non-Dairy Margarine
