So my GF adventure at TDL was interesting. We had the vacation package that included the meal reservations “&more” package. So I had prepaid for 12,000 yen meal at Magellans but couldn’t eat it. It took some google translating but I got them to agree to bring out the meal that was meant for me for my family to share and I would pay separately for my 3300 yen allergy meal. I don’t recommend the package where you pay for the extra dining meals if you have an allergy you will be overpaying. Most of the GF and allergy besides for a vegetarian stew or curry are kids meals. They will not agree to leave off a bun at a hamburger place so you can just eat the meat, I tried at a few.
I ate at the following restaurants:
Oceano Breakfast buffet- I was given a list of what had gluten, this was usually my best meal of the day. I’d have sausage, fruit, cheese yogurt and a salad.
Sherwood Garden breakfast buffet- this one was a bit better than Oceano, had a yummy fluffy egg salad filling separate from the bread.
Magellans - literally a kids meal for 3300 yen was all they could serve me they would not leave off the sauces to make normal course meals GF. I was very disappointed

Canna - I had a better allergy meal here not quite a kids meal but not the fancy food the rest of my family was served.
Polynesian Luau show lunch - this was the one meal that was altered very little and I had the adult portion the same as my family, a couple things were swapped like grilled shrimp instead of the seafood casserole and a different dessert.
Columbia Restaurant - this meal was the best one as the chef slightly altered the dishes my family was being served and the dessert on the menu was gf already.
Vulcana - GF/allergy kids meal with sausage, a small meatball, corn, mini salad and jello cup with apple juice.
My family ate at snuggly duckling and I had two lime jello mousse deserts for lunch and the milk tea. Nothing there other than the unappetizing curry/stew.
Queen of Hearts- GF kids meal again this one had a piece of chicken on it too which was yummy and was the best quick serve GF kids meal of the trip.
Refreshment corner- I had French fries and Ice cream from across the way
Cafe Orleans - Mickey macaron - yummy
I had more jello type desserts in my 4 days at TDL than I have in my life, but they did help sustain me if I needed a quick snack and were on the bottom of most of the special drinks.
My allergy translation card was taken seriously whenever I presented it and a manager would come to take my order and show me the options of what I could get (kids meal

) each time. All of the pictures of what the meals look like can be seen on the TDL on the menu for each restaurant just scroll down to the bottom see the allergy sets, you can also do a filter by allergen too.
