I love bbq!!! I have my smoker running right now! Here are a few pics of my wares.
I hope this gives me some dis cred for bbq.
I do not recall any ribs being sauced before sale to customer. I only recall having ribs at Flame Tree in AK and Cosmic Rays in MK. Flame Tree has a sweet bbq sauce and a mustard base bbq sauce that you can get after you purchase your ribs. The mustard base will have more of a vinegar taste to it.
As far as the rubs, I do not recall if they are sweet. Some rubs have brown sugar and some do not. Personally speaking, I do not pick up much of a sweet taste when brown sugar is used in rubs.
But seeing is believing. Here is a link for food pics at Disney.
