You’ve got a new fast-casual pit-stop for your Union Square shopping trips, and it’s called SC Asian, which opens today in the Macy’s basement food court where Wolfgang Puck Express used to be. They’re occupying the whole half of that front section, including where that sushi bar used to be, and they’re offering a full bar as well as a menu of pan-Asian grub like banh mi sandwich, bao, noodles, and Asian tacos. Note they’re open daily from 10 a.m. to 9 p.m. [Grub Street, Earlier]
