BK was one of the two chains that served its cold coffee pre-loaded with milk and sugar. As such, there were virtually no coffee flavors, and it tasted pretty delicious. When I returned to the counter to ask for a sugarless cup, the counter woman looked incredulous, but gave me a new drink without hesitation and warned that it'd be really strong.
She was not kidding. If I drank this whole thing, I feel like I'd finally be able to finish my screenplay that I haven't started. The taste was a mixture of plastic and styrofoam, with a hint of vanilla that didn't seem at all natural. It sadly missed the deliciousness of the previous incarnation.
