Sushi 21

Behind the modest, slightly worn facade of this Chelsea joint lies a colorful space focused on comfort over neighborhood glamour. The hole-in-the-wall setting is basic, but the kitchen turns out thick-cut pieces, noodle bowls, and tempura. Standouts include the crispy dynamite roll and the value-packed lunch specials, while the staff's readiness to accommodate off-menu custom details—like packing a side of chili oil for takeout—makes the casual experience feel tailored.
