The Bonfamille's location was last used during Christmas 2015 for a brief two-week table service experience serving cajun-inspired options under the name "Scat Cat's Café", and prior to that it functioned as Walt Disney World's test kitchen facility:

In other food-related news, it looks like the Muddy Rivers pool bar at Port Orleans Riverside will soon be installing facilities for limited hot food preparation. Don't get too excited, it won't become a full quick service dining location or anything like that, but there will be simple hot fried food available - french fries, chicken nuggets, wings, etc - prepared to order by the bartenders. See PerfectFry.com for an idea of the sort of equipment they are planning to use, and it seems that connection points have just been fitted in readiness (I have no idea why they didn't do this during the recent two-month refurbishment period, which you'd have thought would have made a lot more sense):
