I got Jack In the Box's faux Big Mac, the Bonus Jack because they were running a special: the $3.99 Bonus Jack Combo. Worse burger EVER. This is probably the worst fast food item I have ever plopped into my mouth. I could not even stand to finish the thing.
So what was wrong with it. The whole thing was kinda mushy. The secret sauce was a bright (almost neon) orange... I guess it's a thousand island but less creamy and more sweet. There was no distinct meat flavor or texture plus the smallish patties were completely overwhelmed by an abundance of squishy bun. In short, the balance was all out of whack.
Do not eat the Bonus Jack if you love your tongue at all! Dead last by a long shot in the Big Mac pantheon (go for the original or the Big Carl instead!). This one's an emphatic "do not recommend!"
