I wasn't a huge fan of the Big Joe bar I tried from Nestle Romania, but this Joe XXL was picked up alongside it and contained chocolate, so I wasn't going to not eat it.
Quadratini, and not much like the Big Joe bar. It was a higher quality wafer, with a tasty cocoa creme filling. Seriously, it was like a squat little bar of Quadratini with a chocolate coating. The wafers are crispy and don't get powdery as you chew. The Big Joe bar from a few days ago was like a stale cake cone meant for ice cream, this is like a properly nice wafer cookie. I actually kind of like it! There are apparently a few different varieties of the Joe XXL, too: vanilla, rum, and quite inexplicably, apple cinnamon. I'd love to try those last two.
I bought both of the Joe bars at the exact same time, so I don't think the quality difference it is an issue of freshness. Unfortunately, I've already thrown out the original Big Joe wrapper, so I can't compare ingredients or sell-by dates. Best I can say is, if you see the Big Joe and the Joe XXL together (say, you're in Romania) and you're craving chocolate, get the Joe XXL. Much nicer than the dried up Big Joe...but still not as nice as a KitKat.
