I ate at a restaurant that served these for their coffee, and while at first I was appalled, I found that the coffee is pretty decent! And you can't beat the convenience of coffee in a tea bag. I'm terrible at making coffee, and I usually only want a small amount (less than a cup) at a time, so making large pots of coffee has never worked for me; I'm always looking for a single serving coffee solution. I recently bought a box of these to take to work, and it's so convenient. (via Shillelagh Restaurant)
