The Blackjack Taco is in Canada now so I'll give one a try soon. That said, I didn't realize that the Cheesy Gordita Crunch was an LTO item in the US but I'm seeing ads talking about how "it's back for a limited time". It's a fixture of the menu in Canada and is usually what I order if I happen to go there. The last time I went to TB a few weeks ago I ordered a plain taco for the first time in ages... wow those things seem bland when you're used to some sort of sauce (sour cream, baja sauce, etc.) on a taco.
