Having lived in Southern California most of my life it was never an issue finding a good sushi place. Now that I live in Las Vegas I depend more on my Yelp friends to steer me in the right direction. And they didn't fail me when I was in search of a fairly close sushi place.
My all time favorite sushi restaurant has to still be Tsunami Sushi on HB, CA (http://tsunami-hb.com/ , http://www.yelp.com/biz/tsunami-sushi-huntington-beach), but En Sushi is a very close second. It has a great atmosphere and very friendly staff.
I started off with an Iced green tea and spicy garlic edamame. The edamame is great. My friends started with an Uni shot, seaweed salad, and had a spicy salmon hand roll.
I had a craving for Albacore sashimi, which is what led me on this adventure, and the chef said the salmon was very fresh, so ordered the salmon and the Cajun albacore sashimi, both were very fresh and tasty. I wanted to try one of there rolls which they have quite a selection of, so I went with the Spicy salmon roll with extra masago. Wow, it was a lot of food but I finished it all.
