Cosmos ClubNightclub in Hoàn Kiếm, Hanoi

Cosmos Club is at 21 Trang Tien Street, Hoan Kiem District — about as central as Hanoi gets, steps from Hoan Kiem Lake and the Opera House. The club describes itself simply as "frequency of the night" and runs Tuesday through Sunday from 9pm.

Where is Cosmos Club?

Trang Tien Street links Hoan Kiem Lake to the Opera House — the easiest address in Hanoi to find. If you are staying in the old quarter or near the lake, you can walk there, which matters on nights when you would rather not arrange a late ride.

A nightclub in the heart of the old quarter

Unlike clubs out on the ring roads, Cosmos sits in the centre. The room is tighter and more focused than the big halls — good for groups who want energy while keeping some privacy.

Opening hours and the rhythm of the night

Cosmos runs Tuesday to Sunday from 9pm. That earlier start suits people who want to eat around the old quarter and continue rather than waiting until late.
