I usually get this when I'm at Kinsa - it's a delicious bowl of beefy goodness - the slices of beef are cooked to a perfect medium and come pretty close to that melt in your mouth feeling. I only wish there was a bit more of that delicious sauce to go with the rice. They have a Wagyu version, but for a regular lunch I'll just stick to the regular gyudon. At about 12++ a bowl, it's one of the more value for money items on the menu. Definitely worthy trying if you're there.
