Cosmos Club Hanoi – Concept Nightclub at 21 Trang Tien
Cosmos Club sits at 21 Trang Tien in Hoan Kiem, one of the most expensive stretches of street in Hanoi and a building it shares with Shark Club. Its concept is “Frequency of the Night”: a universe-themed room, programmed lighting and a stage crew of dancers working alongside resident and guest DJs. The club runs Wednesday to Saturday, 21:00–04:00, per its official page. Table prices are not published — ask the venue on 0799 963 939, or let us check for you free via +84 966 877 714 (Zalo/WhatsApp).

What makes Cosmos different
Trang Tien already holds several clubs, including its own building-mate. Cosmos does not try to be the biggest; it aims at being the most theatrical. Dancers perform through the night, the lighting rig is choreographed to the set, and the room is styled floor-to-ceiling on a space theme — from posters to the stage backdrop. That is why it has a loyal crowd even sitting next to bigger names.
The audience is young Hanoians, groups coming for a specific event, and tourists staying around Hoan Kiem Lake and the Opera House. Watching the DJ and dancers is part of the experience, not background. If you want a bare techno basement, look elsewhere; if you want a night that feels like a show as well as a party, this is the fit.
Hours and the weekly rhythm
Cosmos operates Wednesday through Saturday, 21:00 to 04:00. Guest DJ nights are the busiest and carry higher table prices; the schedule is published weekly on the club’s fanpage and Instagram. Because the room is mid-sized rather than vast, a full house feels packed by 23:30 and a seated table without a reservation becomes unlikely — book one or two days ahead for Friday and Saturday.
Prices and how to plan a budget
Cosmos has not published a table or bottle price list. In practice the club prices by tier — standing, sofa and VIP — and the number moves with the night and the guest booking. That makes a generic price list misleading, so we do not invent one. Two honest options:
| Door entry | Varies by night, confirm when booking |
| Table tiers | Standing, sofa and VIP — quoted per night |
| Drink menu | Beer, cocktails, mocktails, spirits by bottle or glass — per-item prices not published |
| VAT / service charge | Not published — confirm before ordering bottles |
Practical approach: message the venue with your date and headcount, ask for the tier options and whether the quote includes VAT and service. Ten minutes on the phone avoids a surprise at 01:00.
Getting there
21 Trang Tien is a three-minute walk from Hoan Kiem Lake and the Opera House, and roughly 10 minutes on foot from the Old Quarter. It is one of the few clubs in Hanoi where walking is genuinely the best transport. Weekend evenings the street turns into a pedestrian zone, so allow extra time if arriving by car.
How to book a table (free)
- Message +84 966 877 714 on Zalo or WhatsApp with your date, group size and the night you want.
- We check table availability and the price for that specific night with the club.

Good to know
- Open Wednesday to Saturday only — not a seven-night club, so plan around it.
- 18+ with ID checks; bring your passport.
- Dress up: no flip-flops, no sports shorts, and the door can refuse entry.
- The building also houses Shark Club — check which entrance and floor you want before you arrive.
- Since prices are quoted per night, always ask whether VAT and service are included.
