OUR STORY

One Thing, Done Extremely Well

Not a sushi bar, not a ramen shop. A dedicated katsu specialist in Diamond Bar.

Ginkgo Katsu started with a simple idea: a neighborhood restaurant that does one thing extremely well. Not a sushi bar, not a ramen shop, not a Japanese fusion concept. A dedicated katsu specialist.

We named ourselves after the ginkgo tree that stands at the corner of our block. It has been there longer than any of us. Like that tree, we want to be a steady, dependable part of this neighborhood, rooted in Diamond Bar for the long term.

Every cutlet is breaded by hand with fresh panko and fried to order. The bento boxes are generous because our customers are family, not transactions. And our tea drinks are brewed with the same attention as the food, because a great meal deserves a great drink.

What We Stand For

Fresh

Every cutlet breaded by hand with crispy panko and fried to order. We do not batch-fry. Your katsu hits the oil when you order it.

Generous

Overflowing bento boxes and thick-cut katsu that leave no one hungry. We believe portions should be generous, and that value is not a compromise.

Reliable

Your neighborhood katsu spot. Consistent quality, every visit. The same crispy crust, the same fresh cabbage, the same care. Tuesday or Saturday, lunch or dinner.

The Tea House

Our tea drinks are not an afterthought. We source ceremonial-grade matcha, premium oolong from Taiwan, and fresh yuzu. Every cup is brewed to order, because great food deserves a great drink.

Come Hungry

We are open seven days a week in Diamond Bar. Stop by for lunch, pick up dinner on your way home, or order online and earn rewards with every meal.
