Philadelphia Zoo
I haven’t been there, but if I’m going somewhere I am not sure if there will be options for me I always pack myself a GF sandwich and some snacks just so I have a backup plan. On almost every menu you will be able to find a gluten free salad though. Not the most exciting, but you won’t get sick.
