We were able to get buffalo blue cheese, cheddar and sour cream with chives in Epcot at the cart outside The Land Pavilion (near Figment / behind Club Cool- hopefully these directions make some sort of sense). They were still $1.50 per refill if you had the refillable bucket. We liked to mix the buffalo with sour cream. I have heard that there is also maple flavoured popcorn at MK. We are hoping they are still doing the refillable popcorn, especially with flavours, when we return in August. If you have any luck, please let us know
