Set within the Mills Market, this casual concept from Chef/owner William Shen (and named for his pup, Uni) draws a line before it's even open. It's no wonder, as everyone is here clamoring for a taste of their onigiri, on offer until they sell out. The menu is a moving target, with ever-changing availability alongside a host of daily specials like a Japanese curry hash brown (if you're lucky). Made and served in sealed bags, the classic triangles are best eaten immediately while the filling and rice are still warm. It's all spot-on, whether filled with a crispy fried chicken thigh or tuna enlivened with mustard. Unagi is a fan favorite, with cubes of barbecued freshwater eel enhanced with a sweet sauce complemented by the well-seasoned rice.
