I tried this place years ago, and was disappointed because they serve Japanese-style spaghetti, but not on the level of Spoon House in Gardena.
However, my wife read that they serve Berkshire pork and she's a big fan, so we decided to give it another try. I ordered the Tonkatsu dinner and she had katsu-don, and we were both pretty pleased. Mine came with a bowl of chicken soup which was great because I was just starting to get a cold. They also are big on curry but I'm not a big fan. Definitely give them a try. On Las Tunas between Rosemead and SanGabriel Blvds.
