When you live in New York, one thing you can count on is being able to find a Starbucks virtually anywhere—and sometimes even several of them at the same intersection. Filmmaker Mark Malkoff took this observation a step further as he visited every Starbucks in Manhattan in the course of a day, documenting the experience along the way.

In a little more than 20 hours, Malkoff went to, purchased and consumed something at all 171 Starbucks in Manhattan. That meant hitting a Starbucks about every seven minutes and spending $369.14 (which includes $80 for a piece of pound cake after a Starbucks at 96th and Madison had already closed its register).

Starbucks had a good attitude about Malkoff’s endeavor, according to the New York Daily News:

"We appreciate Mr. Malkoff's passion and we applaud his creativity and commitment," said Dan Lewis, Starbucks regional spokesman.

Commitment is one thing it did take. Over the span of his 10-minute video, viewers can see Malkoff planning the day, trekking around the city on a bike and getting increasingly caffeinated and dehydrated. It’s hard to imagine how he slept after downing at least 50 caffeinated drinks in 20 hours. Or maybe that’s just what it takes to become the next big viral video star these days.
