It goes for $2.89 in my neighborhood but I opted to get it in a $5 Box that also includes a Crunchy Taco, Doritos Locos Taco, and medium drink.
While it's called the Cheddar Habanero Quesarito, the new menu item is just a regular Quesarito with the addition of Habanero sauce (despite the name, there's isn't any more cheddar to it than the original version). It's the same sauce that was featured in one of the since-discontinued Dare Devil Grillers.
Beyond the sauce, you get the same mostly nacho cheese oozing out of the quesadilla and the very familiar combination of Taco Bell's signature seasoned beef and rice. It's nice but very well-trodden ground.
