Best Sushi Restaurants in Diamond Bar

Definitely one of the better quality AYCE around!!! Service was great. They were very attentive. They have a system - there is a sign on the table that you turn if you need service. Sushi was fresh and delicious. Rolls were great and not too overloaded with heavy sauce. They are pretty strict with their eating time (1 1/2) but we were full at 1 hour and 15 and didn’t even order a 3rd round. Recommend going with at least four people to make sure you experience a greater variety of rolls as they don’t do half rolls. Make a reservation to limit your wait. Would definitely go back!!! Yummy!!!

We have been coming to Ra for the past 4 yrs for our Misfits Christmas! Matt is the best server and always so happy to see him every year as part of our tradition! Love the food the staff ! See ya next year!

We had a great Christmas Eve dinner at King's Fish House. The food and service were excellent. We've been to the Corona location a couple of times but first time at the Rancho Cucamonga location. The quality of the dining experience is consistent no matter which location you choose to visit. King's Fish House is our favorite seafood restaurant. We'll keep coming back!

The service was a little slow, but all the employees were running around like crazy trying to take care of everyone so maybe short staffed. Pretty good sushi, and pretty good views. We sat outside, but the radiant heaters kept it warm enough even in December. It seems like an Instagram restaurant to me: Most of the people were just there to post photos for their friends to see. The unagi nigiri was definitely the best thing we ordered. The Yuzu cake was great too.

The food was great. Hubby is not a sushi fan, but found good options. Lance, our server was great.
