Last time I went, we went to eat at Pecos Bill in Magic Kingdom and my Mom and Sis split the chicken wrap, it's big and it comes already cut in two nice pieces with a side of fries. Also at the same place, I ordered a bacon double cheeseburger for the kids to split, I asked for an extra bun and was ready to pay for it, but they gave it to me, then you can garnish it to your liking. It also comes with a side of fries and it was plenty for them.
But I would also love to know some more places that I can go and split some meals ha!
I have split meals with my sis at House of Blues and Rainforest Cafe, their plates are big.
