We didn't have the chicken parmesan, but a lady sitting next to us had it. Hers came with noodles. She said it was very good.
I'm not sure if a milkshake is available. The only time DS got a milkshake on the dining plan was at Pinocchio Village Haus, and it had to be counted as a dessert. Oh, and at Whispering Canyon Cafe he was able to get a bottomless milkshake as a drink.
You can get chocolate milk, Powerade, soda, bottled water and things like that.
There is a pretty good assortment of desserts. When we were there they had slices of cake, cheesecake, donuts, fruit cup, pie, cupcake, brownie, Mickey head rice krispie treat, etc.
When we were at Pop we got the pizza (not so hot), meatball sandwich (tasty), burger (tasty) and chicken fingers (tasty). I only had the meatball sandwich. My family had the other things.
