Comma is a night bar that treats the selector as part of the draw. Its Dischogs sessions are built around DJs playing from their own collections: vinyl, rare cuts, neglected favourites, and records chosen for the room rather than a peak-time formula. House, disco, downtempo, and slower listening sessions all turn up in the programme.
The bar is more social than a jazz kissa and becomes properly late-night when the guest DJs arrive. That makes it the right Hanoi pick for listeners who still want the energy of a crowd. Check the programme before going, then arrive for the selector rather than expecting the same musical pace every night.
