Asian fusion restaurant Shoyu is a good dining option if you are transiting through MSP. I had the Tantanmen... mildy spicy, and delicious. I also had a couple of spoonfuls of my wife's shoyu ramen, which had a fantastic mouthfeel, no doubt due to the copious amount of collagen in the stock. I also had a refreshing cocktail that had sake and cucumber in it. Of course, since this is in an airport, the price is high, but that is to be expected.
