The BBQ Beef Brisket Sandwich is one such mystery. After the beloved sandwich was discontinued, Costco never confirmed a reason for taking it off the menu -- but the internet has several theories.

Of all the strangely delicious food at Costco's restaurant — hot dogs, pizza, that un-classifiable "chicken bake" — there is one that completely eclipses the rest: the BBQ beef brisket sandwich.

I eat at the Costco food court less often now ever since it replaced the Hebrew Nationals with what I sincerely believe is the far inferior Kirkland brand; but recently, I began eating there again ...

I ordered Costco's BBQ brisket sandwich, hot dog, chicken bake, churro, and a soda. The whole thing cost just $12, and I was blown away by the food. This video was originally published in March 2016.

The verdict on Costco's burnt brisket ends and pulled pork: You could do worse, especially if you're looking to spice up a weeknight meal and avoid the lines at your favorite smoker.
