These are good, they taste a lot like ham (and similar color too) because they're smoked.
We first tried the turkey legs at Magic Kingdom, then again at MGM. It is a lot of meat, too much for a light eater to manage alone, but good to split. I recommend getting them at MGM for two reasons: 1) better to eat smoked/salty/greasy food with a crisp, cold beer than a sweet soft drink, and they don't sell beer at MK; and 2) there's a little handwashing area/sink right at the fruit stand near the seating area where they sell the turkey legs, so you don't have to run around looking for a washroom
I recommend getting some plastic forks and knives at the condiments station and cutting the turkey leg up, it's heavy and rather warm to hold starting out, and you don't really need to gnaw it until you've cut some of the bigger pieces off. Pick up a few honey mustard dips and lots of napkins before heading out for your table. Oh, and you may want to be carrying dental floss or some toothpicks to duck into the washroom with later...
We usually get them at the American pavilion in epcot and eat at a table outside. They are a favorite for our kids. very reasonable price for a quick lunch. Sometimes there is a cart outside that sells them, but if the cart is not open you can order them from the CS restaurant there even though they do not appear on the menu.
