This former Soviet-era fish restaurant with a wraparound balcony overhanging the east bank of the Mtkvari River is a great space for a nightclub. Mtkvarze (literally, 'on the Mtkvari') often hosts well-known international DJs playing that Georgian favourite: minimal techno. There's all-night food, too, and once you're past the door, it's a super-friendly and welcoming place.
