There are a handful of eateries in the HEB Mueller food court, but our favorite mid-grocery pitstop is Roots, where the specialty is duck fat fried chicken in the form of wings, strips, and sandwiches. It’s a well known fact that duck fat makes everything taste better. We like the Spicy Bird, topped with kimchi mayo, giardiniera, and kale. It adds some great texture to some incredibly juicy chicken.
