My favorite CS use to be Pepper Market. I loved the setting, the variety of foods offered, and actually the whole different way it was set up BUT we just returned from a short trip and had dinner there. I was so disappointed.
Some the parts are closed up like the Wok and stir fry section. Other menu items are just plain gone, like the steak and baked potatoes. I would no longer recommend Pepper Market as an even a good CS.
Since you are staying at the POP you can visit Pop's CS area. The food is pretty good, there is a fine variety and the CM are helpful. We all tried something different but I had the Parmesan Pasta Chicken and it was quite tasty. DH had the fried chicken dinner and said it was good too. They have special that change with the night of the week.
We also had a kind CM explain that for dessert we could have anything from the sundae bar area. He stamped our receipt and that allowed us 90 minutes to eat and then return to have them make us a sundae. I had a hot fudge sundae where I picked the flavor of the hard pack ice cream. You could choose toppings also. I had hot fudge, nuts, whipped cream and a cherry. It was good.
We also enjoy Cosmic Rays in Magic Kingdom. I think the rib and chicken dinner is quite good. You get smashed potatoes and a vegetable along with a dessert and beverage. My one DD is a vege and she had one of the vege entrees a few years back and said it was good. She was not with us this trip. Be aware there are three different stations there, each with their own menu. Their fixings bar is quite the spread. We all love their mushrooms.
We had a pizza and sandwiches from Wolfgang Puck express. They were pretty good too. It is in Downtown Disney near Cirque.
On the other side of Downtown Disney is Earl of Sandwich. We have had good sandwiches there in the past. It gets super crowded right at lunch time.
Those are some of our favorites. Hope you find the ones you like best too!
