Opened by the team behind Shunjuu Izakaya and located within the busy China Square Central area, Koji Sushi Bar offers a selection of nigiri sushi, sashimi and omakase sets. However, their most popular item is their donburi (rice bowl) -- choose from options such as salmon avocado tartare, tuna tartare, pork cheek and eel. At $17 per bowl, they are one of the more affordable donburi options around, considering the quality of their ingredients. The must-try here would be their sashimi rice bowl - sashimi servings are generous and the crispy tempura bits add a surprising crunch factor.
