I tried the new "Bacon Insider" burger at Jack in the Box last night. I was excited when I saw the commercial, because it looked like it might be pretty similar to the "bacon bacon burger" they discontinued years ago.
The Bacon Insider comes with slices of bacon, bacon mayo, and bits of bacon inside the beef. It comes on a brioche bun that is completely different than the brioche bun at Wendys, it's more similar to the bun on the fish sandwich at BK.
It was pretty good. I would definitely order it again. The taste of the bacon mayo reminded me of the previously mentioned 'bacon bacon burger' but with the nicer bun, lettuce, tomato, and baconized beef it was a good main item. I don't know how long it will be around, my favorite burger at JITB is the Ultimate Bacon Cheeseburger, the Bacon Insider is a close 2nd for the time being.
