The Pi is a neighborhood cocktail bar in Ho Chi Minh that serves cocktails inspired by Vietnam and Southeast Asia. Its signature drinks include the Ultimate Martini, which is high in alcohol and strong in flavor, alongside original cocktails that are refreshing with layered aromas. In September 2024 the bar changed its drinks menu and adjusted the lighting to be darker and softer, and there is a separate room at the back that seats several people. Bartenders recommend drinks and guests talk among themselves at this neighborhood bar.
