I picked one up for $5.39.
Bacon fans and those of the meat-and-cheese set will most likely find a lot to like here as the burger offers much in the way of bacon-y and meaty, cheesy goodness with few distractions.
The beef was pretty moist and the seasoning set off the beefiness well. The grind had a nice coarseness to it and the patty size was just right.
The onions complemented the beef nicely and retained a bit of that watery crispness. There was a sweetness as well. The bun also added some sweetness to go with a soft and spongy, but resilient, feel.
Overall, Jack in the Box's Triple Bacon Buttery was very enjoyable and super bacon-y. The different forms of bacon actually gave some variation and depth to the overall bacon-iness. However, if you dislike the greasy mouth feel of bacon fat (there was a bit of it dripping around), this burger's probably not for you.
