Tana Market is without a doubt my favorite convenience store in America! Besides the usual selection of junk food, they also have an aisle devoted to Ethiopian spices (afrij, a deep orange powder made from hand-picked peppers, is also my favorite spice ever) as well as tea and other things from Ethiopia. They even have a couple Ethiopian (excellent) beers at very competitive prices. This might be the only convenience store I know of anywhere that's worth making a special trip out of your way to.
