Described as "a quad shot of espresso with cayenne" by co-owner Mike Hartkop, the drink changed everything we previously knew about espresso drinks. Fiery cayenne burns through immediately, while the four espresso shots finish wrecking your nervous system. It was an unbelievably enjoyable experience that we're fairly sure we wouldn't live through twice, but would be compelled to attempt.
Asked about the popularity of the drink, Hartkop offered this:
It depends on who’s working and how tired people are. We do sell quite a few of them. They’re one of our signature drinks. Some employees really enjoy the Bull Breaker and some are afraid of it.
