I have seen a lot online about Churros in the American Parks but not so much in Paris and was wondering if they actually sold them in Disneyland Paris :D
No, they don't :(
Only as part of meal in one of the counter service restaurants
The last I saw (last year), you could buy them from Fuente Del Oro restaurant for about €3.50. They are on the dessert menu and could be purchased on their own but of course, that could have changed.
They also sell them at the little cabins which are in the village during certain seasons.... Definitely seeing into spring and Christmas
They are not the same churro as in Disney World, they are much smaller. They're still nice but they are not the long fresh churro
