Start your meal by letting your server suggest a fresh nigiri. Ours talked us into the delicious white tuna, aka butterfish, which melted on the palate just like its namesake dairy product. Maki rolls are generous and elaborate, such as the aloha roll—eel and cucumber topped with white tuna, avocado, and a sweet unagi sauce—or the golden bear roll—tempura shrimp, avocado, and crab topped with a rainbow of fresh salmon, tuna, unagi, and tobiko, drizzled with spicy sauce. Oyama has all the other classic offerings of American sushi joints, such as agedashi tofu and soft-shell crab, but some of the dinner entrées are poorly executed for the price, including our overcooked grilled miso bass for $19.95. Lunch Mon.–Sat., dinner daily.
