Since you asked (and even asked for more detail the better) I will gladly write about Roaring Fork. Are you ready, because here it goes...
Roaring Fork is WL's quick service snack bar / restaurant. It is located near the pool, down a long ramp from the main lobby in the North wing of the resort. It is also the mug fill station for the refillable mugs that you get with room packages or you can purchase for $15.99 that entitles you to free soda, tea, and hot beverage refills for the entire length of your stay.
On the
Disney Dining plan, the meals here are Quick Service and for lunch and dinner they include a dessert. There are also a lot of dining plan snack options available here, from drinks to desserts to even hash browns at breakfast.
For made to order food, there are two service counters where you wait in line and order one of the items available at that station. At breakfast, one station has typical bacon, sausage, pancakes, and biscuit breakfast plates, while the other has Mickey waffles topped with strawberry, chocolate, or bananas. For lunch and dinner, one station has burgers, fries, chicken, and another daily special. The other has different items, like sandwiches or even spaghetti and meatballs depending on the day. There is a dessert cabinet with pastrys, cookies, and the biggest and best chocolate brownies that we saw anywhere on property. They could easily be split between multiple people, or even over multiple meals. (I liked having the leftovers with breakfast). Once you collect the food that you want, there are cashier stations where you pay for everything you wound up with.
Then there is an adjacent dining area with tables and chairs where you cna eat your meals if you choose not to take them to the tables outside by the pool or up to your room. This area can get pretty crowded during busy times, but is a nice place to sit and eat.
While the concept is similar to quick service at other Disney Resorts, I found the quality to be better at Roaring Fork. This time I had the bacon cheeseburger at the Poly, Coronado Springs, and RF, and by far preferred the one at RF. It just tasted better, came with fresh hot fries as a side, and had lots of good dessert options. There are also daily specials, ranging from cheesesteaks to various flavors of flatbread sandwiches which often looked interesting.
During our 10 day stay we had a dinner and two lunches at RF, and we had at least four breakfasts from there. At breakfast we would often share either a breakfast platter or waffles, and usually would take them up to the room. I would have been perfectly happy having many more meals there, since it is so convenient and I really enjoyed the food.
RF is definitely not a fancy sit down dining experience, but it is a great compliment to scheduled ADRs since you can always stop by and eat something whenever you are in the resort, and you have lots of options as far as how much you want to eat. During our trip they were open from 6 AM to midnight, with hot food from 7AM to 11 PM.
