They did do a bag check, but they only checked one part of our backpack, even though our backpack had multiple zippers/openings. You are allowed to bring outside food in though if you have a dietary restriction. We are vegan, and there are currently no vegan options at any of the restaurants inside the park. If they did check the part of our backpack that we had our food in, we would have let them know our dietary restrictions, and they would have allowed it.
