Well, that was one hell of a long title. The original three Grillers (Beefy Nacho, Spicy Chicken, Loaded Potato) came out quite awhile ago. With the senseless removal of the Volcano Menu, the Spicy Chicken Griller has been scrapped, and these two have been added -- both $1 for a limited time.
The Chili Cheese Fries Griller is pretty simple: chili, nacho cheese, and potatoes. It's been awhile since Taco Bell has had chili nationwide, so there's something for people to get excited about. I thought this was a pretty good Griller, and at a very good size -- I think somebody overstuffed mine, not that I mind. This Griller is a lot like the Chili Cheese Burrito, just that this adds potatoes, which adds an extra bit of texture and flavor. While I'm not crazy about Taco Bell's chili, it's still good for what it is. Between this potato-centric Griller and the Loaded Potato one, this one is quite a lot better. 4/5
The Chipotle Ranch Chicken Griller I was hoping I'd like a lot, since it was replacing the Spicy Chicken one, which had lava sauce. It's certainly good, but it's not new at all. I'm fairly certain it's the same sauce that's on their Smothered Burrito. That's not a bad thing, but it's nothing I haven't had from Taco Bell before. I actually like the addition of the sour cream in this Griller as well. 4/5
These are definitely my two favorite Grillers now. The Beefy Nacho one is boring, as it's just meat and cheese with soggy red strips, and the Loaded Potato one is okay, but really salty with unappealing pieces of "bacon". Both are well worth a purchase. At the $1 price, it's a no-brainer.
