Boss Black was my go-to when I visited there, and I loved that I could get it either hot or cold depending on the vending machine, for less than a dollar. I tried a few other Boss flavors – I remember the Rainbow Mountain being godawful.
Good news! A cup of coffee at Starbucks is about $1.80 these days. Still dark and char-flavored, but given the lines out the door every day, that’s some people’s idea of a good time.
I went there as a vegetarian and became a pescatarian almost immediately out of necessity.
