On Friday nights, three best friends meet in the alley outside their favorite place, an underground Seattle speakeasy hosting touring jazz legends, home to raucous gambling, and even louder dinner parties. Lee, Min, and Ada are unlikely playmates but they all share the same dream: to own and run their own restaurant and jazz club. When the bombing of Pearl Harbor and rising WWII tensions tear apart their homes, they make a sacred promise to keep their dream alive. Spanning three decades, 7th and Jackson pairs local history with cultural diaspora and live music, all on one plate.
