Tonga is lively well into the evening, generally becoming suddenly very quiet at around 23:00. Expect to see people walking around until late. Beer and liquor are available from many outlets, including Fijian, Australian and New Zealand imports to complement the local brews. If you are keen to check out native drink, try Kava (something like liquid novacaine) at least once.
