I have a million and one different allergies. I'm allergic to dairy, peanuts and treenuts and on top of all of that, I'm also vegetarian. I really wasn't scared at any of the meals. They had a separate table for people with dietary restrictions. Everything was made separately and was kept separately. 

Although they are very accommodating, I also would recommend bringing some ramen cups with you in the unlikely event that you don't feel comfortable eating what they have. The staff is also very open to helping you as much as they can and if you have an issue with food, they're willing to do whatever they can to fix that for you. If you are like me and have lots of food allergies, eating with allergies really should not be a concern at IC, and don’t let it get in the way of you having the best time ever!
