Starbucks (NASDAQ:SBUX) is doing just about everything right these days. Profits spiked higher last quarter, and the coffee king's sales growth is the envy of just about every other retailer. But there was one metric that stayed stubbornly low last quarter: food sales.

Despite the push into an expanded breakfast offering, and the beginning of a national rollout of new bakery products, Starbucks' food sales were stuck at just 19% of all sales -- exactly the same as in the prior three fiscal years running. In the video below, Fool contributor Demitrios Kalogeropoulos discusses how that's a disappointment, and what Starbucks can learn from Panera Bread (NASDAQ:PNRA.DL) when it comes to selling more food.
