Natural light floods the dining room at Sushi Hil, where blonde wood furnishings set a clean, contemporary tone. The best seats are naturally at the counter, where guests can watch the talented and engaging Chef Hil Nguy craft his jewel-like pieces with great care and efficiency. Seasonal ingredients and high quality fish shine, as in a dish of Japanese sweet prawns accompanied by the just-removed head, served simply over crushed ice with a dab of wasabi. Aka Isaki, or red grunt, is served with orange to underscore the power play of salinity and citrusy sweetness, while aji (mackerel) from Kagoshima has an added zing with grated ginger-scallion. Other standouts include otoro, ikura and chopped tuna, and black throat perch.
