Koo has been serving sushi in the Inner Sunset since 2004, built on daily deliveries from the fish market and a kitchen staffed by traditionally trained sushi chefs. Beyond standard nigiri like uni, unagi, and hamachi, the menu runs through hot plates such as miso marinated black cod and starters like ankimo, alongside an omakase option where the chef selects according to what's fresh.
The Spoonfuls of Happiness — paired spoons of uni and ankimo served with a shot of sake — has become a table ritual here, and the Koo Roll and Two-Way Scallop round out the restaurant's signature dishes. Rotating catch-of-the-day specials keep the seasonal offerings moving alongside the standing menu.
