Coffee has become big bucks for convenience stores as customers have embraced a cheap brews.

Seven-Eleven, the chain responsible for kicking off the craze, now wants groggy morning workers to eat something with their cup of joe. They've rolled out — and heavily promoted — a new line of donuts, which are displayed prominently next to the coffee machine. Most varieties, including strawberry and "old-fashioned," retail for ¥100, while a few fluffier entries (sometimes stuffed with cream) cost ¥110.

The next time you miss breakfast, you could do a lot worse than one of these donuts and a coffee.
