Easily the number one item for me would be mcdonald's mighty wings. I loved those. Just breaded chicken wings with a bit of spice, but other than kfc no one offers wings at fast food places and kfc is too far away for me. Plus mcd's wings were a lot meatier.
Did anyone explain the double down yet to the non americans? It's this:
Two breaded and fried chicken breasts with bacon, cheese and sauce in between so it's like a bunless chicken sandwich. I don't think I actually ever had one cus there aren't any kfcs close around here.
That naked chicken chalupa thing looks nasty. But I might try it cus everyone is giving good reviews. It's got a lot in common with double down actually.
Taco bell constantly comes out with new things and then drops them. Most of the time I don't care cus they either suck (like the chickstar abomination) or cus they aren't as good as other offerings, like pretty much every new burrito they come up with. But I still crave lava sauce from the volcano menu to this day. It was basically like a creamy chipotle sauce, but sooo good. They recently had a habenero sauce which was close but not the same. So if they just brought back that I would be ecstatic.
Also before it became the XXL stuft burrito it was just called the grilled stuft burrito and it was great. For one it was a hell of a lot cheaper, debuted at $1.99. Now I think it's $3.99 for the xxl. And it comes with guac which I despise taco bell guac so I just remove it anyway. And it had this awesome pepper jack sauce called baja sauce which they also discontinued. The new XXL version is mostly tortilla and doesn't feel as full. The original was the perfect fast food burrito.
Recently taco bell had these things called double stacked tacos. They were a crunchy taco but with some sauce and a soft shell wrapped around the outside, like a double decker. One had nacho cheese, another had a habenro sauce. And inside had more stuff like sour cream or sauce. They were good, a worthy upgrade over a regular taco but the real kicker was they were a buck. For comparison a regular taco is $1.09 and a supreme with sour cream and tomato is $1.49. So they were 50% less than anything remotely comparable and awesome. Maybe that's why they didn't stick cus my guess is TB couldn't afford to put that many ingredients in a $1 item.
It looks like they might be testing that potato burrito thing in the US right now:
