Filling portions, accommodating staff, and most importantly delicious food. Izakaya style allows for small eats if needed (especially during happy hour, see posted). Their bento portions are more than fair and their staff will work with you no matter the circumstances. Major recommendation for casual dine-in and/or after work celebration.

Came for La Sierra University Volleyball game. My son’s team is playing against Hope University.
Drove for 1,5 hrs. Super hungry. Decided to try “Kopan sushi and ramen”.
I choose nabe, older son choose a ramen. And we ordered a sushi.
Restaurant inside is like a real japanese “izakaya”. Chef is japanese!
Food is delicious, hot and fresh! Price is a not too expensive expensive and not too cheap.
Recommend this japanese restaurant to everyone who loves a real japanese food.

If seated in the patio area, customers tend to be forgotten. Need to go over to the main restaurant to grab someone to take our orders.
Other than that, food was good. Price is medium to high due to cuisine.

I absolutely love this place. I eat here every chance I get. The veggie ramen is absolutely delicious and I just can’t get enough of it. Staff is always friendly and food comes out pretty quick even during busy dinner hours. Every once in a while an order gets mixed up but the mistake is always corrected. This is truly a delightful place to eat.

my bf and i are regulars here. we never have to wait long, even if the waitlist says it could be up to 20 minutes, it's never touched 10. service is quite good. once in a while we have to ask for waters or the check but it's never a hassle. food quality has always been great and the atmosphere is great too. even though i am never the one that pays, the prices are awesome too. love this place.
