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. Everyone is 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. Made and served in sealed bags, the classic triangles are best eaten while 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. Check out their sister spot, Cowboy Curry, also located in Mills Market, with tasty, humble Japanese curries.
