Fans of real-deal sushi-bar Nipponese are united in huzzahs for Rokai, a sliver of a restaurant in a low-key, high-end section of the Cuauhtémoc quarter, north of the Reforma. Japanese-born chefs Hiroshi Kawahito and Daisuke Maeda change up the menu daily, depending on what’s available at markets (they make great use of some of the best fish that comes in from Baja California); regulars like to nosh omakase-style for a multiple-course tasting at the chef’s discretion. Quality sakes add a rosy glow to the precision with which every creation comes over the bar in this spare but fashionable setting. Reservations are recommended.
