It's been 10 years since the last time I was at Chefs de France I enjoyed it but I felt like the tables were on top of each other. We went to Tutto Italia last year and loved the food and service was amazing. I wish I would have ordered the steak a tutto italia because my husband did and I loved it.
Both menus have been two of my favorites in World Showcase, and both have an upscale feel to the dining rooms, so I'd just compare menus and decide what cuisine appeals to you more. But I think both are excellent choices!
