Not just a sushi joint (though the sushi chefs heartily greet all patrons who enter), this bustling lunch-and-dinner spot in downtown Coral Gables offers daily specials -- scribbled in kanji and English on blackboards that run the length of the east wall -- depending on what's fresh. A treasure on the regular menu is the spicy kimuchi ramen, a fiery interpretation of traditional noodle soup, a bright orange broth brimming with sliced pork, bean sprouts, and spicy kim chee. Other noodle dishes are uniformly excellent. The sushi is superb as well, and without the scourge of cutesy nicknames for different kinds of rolls that plagues so many other popular sushi bars. One indicator of the quality: At any given time, the restaurant seems to boast at least one party of Japanese businessmen who have sauntered across the street from the Omni Colonnade.
