We've travelled twice with 10, and the only place that had a difficult time with us was th Maya Grill at CSR- all ur meals came out at different times- my parents had ordered dessert and my dh had just gotten his meal-lol!
Over the two trips, we ate at: Boma, Ohanas, Kona Cafe, Teppan Edo ( this was a tiny bit squishy b/c the tables usually sit 8, and we were 10, although 8 adults and 2 children. If many of your party is Pooh sized, you may want to skip this option) Biergarten, Crystal Palace, Mama Melrose, Sci fi ( separate cars but right next to each other), Le Cellier, Raglan Road and Kouzinnas. I think b/c the Disney restaurants are so used to serving large groups that it's not like going to the local restaurants where they only get a few a week.
