At tiny Osaki’s, you’ll wait to get a table where you literally rub elbows with other diners, a minor indignity that’s forgiven with the first mouthful of artful sushi and sashimi with freshly grated wasabi. Serious sushi lovers always choose the omakase menu and let chef Takeshi Osaki surprise their palates. Bliss is a cup of sake and a sweet fried softshell crab.
