Located between swanky Russian Hill and gritty Polk St., Tonic SF is a local bar that just says SF Americana. The red vinyl booths and long counter top harken to the 1940's while their modern mixology is so San Francisco. They host a weekly trivia night and Guest Bartending events for charity (you can get behind the bar from 6:00-9:00, Thursday, Friday or Saturday to raise money for the charity or non-profit of your choice).
