New menu items are developed and tested at this Shake Shack flagship in the West Village, where you can weigh in on in-development dishes such as Chick’n Bites, breaded breast meat morsels with barbecue or honey mustard dips. With your positive feedback, a veggie burger or the black sesame shake could appear on menus elsewhere. Ordering is done at touch-screen kiosks, and there is plenty of seating at tables or along a counter.
