Just as Breanna said, I find it easiest most of the time to just make it work. Fries and salads are usually the safest options, just be wary of cheese on the salads. One warning to always remember is to be very careful with vegetarian meals. Vegetarian meals are rarely good for PKU diets because vegetarians need the same amount of protein in their meal without the meat, while PKU diets need considerably less protein from the meal. As a result, vegetarian meals are usually loaded with cheese, beans, etc. so just make sure to double check.
