Honestly, there is no place I enjoy dining at more than this non-descript sushi establishment in Little Tokyo. Everything my friends and I have sampled on the menu - toro, albacore, salmon, shrimp, yellowtail, spider rolls, soft shell crab, miso soup, asparagus tempura, chicken teriyaki, and more - has been absolutely impeccable in both taste and quality. I've been to NoBu and Sushi Roku before and genuinely give this place higher marks. The sushi chefs are even really cool (Abe, Mark, and I have our own set of inside jokes). The two primary reasons why this places stands out above all others in terms of food quality are quite simple - exceptionally fresh seafood and amazingly tasty seaweed.
The ambiance is not as high-brow as you would expect from such a fine sushi establishment, but that's easily forgivable in exchange for their moderate prices (I end up ordering around 6 items and my tab usually comes out around $40). The restaurant also has a VIP room that is usually filled with Japanese businessmen, although I prefer to sit at the sushi bar (there are also tables in the main dining room).
The main drawback of the place is the shadiness you confront between your car and the restaurant (there is some skeezy nightclub on 2nd Street that brings in its share of hooligans).
