Rokuan

Rokuan is a little ramen/sushi shop that is at the end of Chino Hills, right next to Diamond Bar. I've been to all of the ramen shops and Rokuan is the best hands down. Their broth is unique, delicious, and extremely flavorful. Prices are very reasonable. Forewarning: do not bring small kids here as they have a rule about this and double check their times because they have odd hours of operation. Skip every other place in Chino Hills and visit Rokuan. It's not like ramen in LA (or Japan), but it totally beats the drive, traffic, and wait time.

Delicious and authentic Japanese food. Service was fast and friendly. We ordered the Tonkatsu and Curry Ramen. Both were well-presented and delicious. The flavors brought us right back to the time we had spent in Japan. I highly recommend stopping by.

Very simple sushi here. Don't come here for your happy hour rolls you won't find it. There sushi is top grade and delicious!! Very generous cuts of sashimi and sushi. Oh and they have this thing called ramen here that's is the bomb! Gotta try it

I had the spicy black miso and my wife had the tonkatsu ramen with the spicy garlic sauce. One word: UNBELIEVABLE!! The broth is rich in flavor, the ramen is cooked perfectly. A nice feature they have is the combos. You can order a poke bowl, 1/2 or full sushi rolls along with your ramen. The restaurant was clean and well arranged. The owners were very hospitable.

We've known this place for just under 14 years. Same caring and wonderful owners. Same top quality sushi and great service.
No compromises!
Wish we could eat here twice a week!
Best sushi in Chino Hills!
