I had been to this place for several times.
For the first few visits I tried udon and katsu and those are all pretty decent. I would have given it 5 stars if that's all I tried.
However, I ordered beef Teriyaki the last time and the beef is too hard to chew, and I would give it only 3 stars or even 2 stars for its beef Teriyaki.
So 4 stars in general.
