A nondescript facade and a location tucked amidst forgettable neighbors mean you could miss Sushi Jin, but don't. This place is tiny but mighty, with room for just six at the bar, plus two additional tables. It is something of a local secret, but those in the know come here for traditional Japanese served with a distinctive voice. Begin with otsumami like live lobster sashimi topped with osetra caviar in an olive oil and thick, savory soy sauce finished with fresh satsuma rind.Ankimo in a ponzu bath is brilliantly simple yet luxurious, followed up by miso soup in lobster broth that is far from humdrum. Nigiri, from hirame to anago, balance sweet and salty, but the otoro with Hokkaido uni and white baby prawn is as pretty as it is pleasing.
