The last time I checked, the Jack-in-the-Box regular fries had NO milk
ingredients.  The curly fries DO have milk ingredients.  My daughter
eats a JitB hamburger kid's meal with no reaction - and she tends to
react to very small amounts of milk protein.

I believe that the same is true at Carl's Jr. - the regular fries are
safe, but the criss-cut fries have milk products in them.

My daughter likes her hamburgers ketchup only.  One of the two
restaurants mentioned above has a "secret sauce" regularly on the
hamburger.  When I checked for safety about 1-2 years ago, the secret
sauce was safe.
