Tutto Italia Ristorante is located in the Italy Pavilion in Epcot. The chef is always available to discuss any allergy options. There aren’t many options because everything is meat- and dairy- heavy, but I was super satisfied with what I had.
I ordered gluten-free pasta with the marinara sauce and a side of green beans. Let me tell you, the pasta sauce was probably the best I have ever tasted. EVER. I could probably subsist on eating this and only this for a very long time. It was that good.
