Used to be "Pepper Lunch" but the company replaced most of the PL branches with "IkinariSteak" in Japan, which is now much better quality at a higher pricing. Over 100 branches in Japan as of September 2016. You should be able to find one that's relatively close to where you stay. Lunch is fairly reasonable and even dinner isn't expensive at all. If you are a beef person, I say it's worth a try.
My rating: 4.0
