Jack in the Box Teriyaki Sauce does not have a black belt in flavor. It is teriyaki sauce and will always be just teriyaki sauce. Is it good, well, it's teriyaki sauce. I wouldn't say it stands out in any way. I wouldn't go to Jack in the Box for it or horde it if I went there.
It is, it is fine, it is something you should get if you like teriyaki and you go there.
