I have traveled far and wide and had milkshakes across both coasts, and none rival those of Texas-based Whataburger, which just announced today that it is releasing a coffee milkshake [1] for afternoon pick-me-ups. The superthick texture (you almost can't suck the milkshake through the straw), the sweet vanilla taste, and the salty finish make it impossible to deny yourself a Whataburger shake when it comes time to order. It's one of those menu items you definitely can't split and certainly can't waste a drop of. That's why I know the new coffee flavor is bound to be perfection.
