Reika Yo on Where (and What) to Eat During Japanese Restaurant WeekSharpen your chopsticks: Many of the city’s best Japanese eateries are offering prix fixe meals and signature dishes for Japanese Restaurant Week, which starts Sunday and runs through March 10. (Get the details here.) We asked Reika Yo, the owner of EN Japanese Brasserie, to give a primer, in her own words, for those who think Japanese cuisine begins and ends with sushi (and what’s sashimi again?) and provide picks to go along with it. (The excellent EN Japanese Brasserie, by the way, is an elevated version of an izayaka, where you find many small, rustic dishes.)
