Even though Cyros Sushi and Sake Bar, 6601 Morrison Boulevard, has only been open a short time, proprietor Cyro has been around the sushi block a few times. Cryos is small. This is not the kind of place with oshibori (hot towels), kimonos, and shakuhachi music. But Cryos isn’t a raucous kind of place either. The only kind of vibrancy here will play out on your plate. The best I had this week was Cy’s signature roll: the Avante Garde ($11), with ahi, crab, avocado, and sprinkled with crispy microplaned bits of shallots and garlic. This is not a traditional roll, in fact, Cy will tell you (if you sit at the sushi bar) the roll has enough sauce that it shouldn’t be dunked in soy, and enough heat that wasabi isn’t needed either.
