Opium is one of Soho's most distinctive nightlife experiences, hidden behind an unassuming door on Gerrard Street in the heart of Chinatown. Spread across multiple floors, the venue combines ornate cocktail bars with a late-night dancefloor, offering something quite different from the typical London club. Its speakeasy-style entrance and exclusive feel mean that the door policy matters, and arriving without meeting the age and ID requirements will prevent you from discovering what lies behind that famous green door. Here is everything you need to know about the age policy at Opium.
Minimum Age at Opium
Opium requires all guests to be at least 18 years old. This applies on every night the venue is open, whether you are visiting for cocktails in the early evening or staying for the late-night club session. Opium does not apply the informal 21+ preference that is common at Mayfair venues. The 18+ policy is enforced consistently for both men and women, on weeknights and weekends alike.
This makes Opium one of the more accessible upscale venues for younger guests who want a premium experience without worrying about gender-based age discrimination at the door. As long as you are 18, have valid ID, and meet the dress code, you are eligible for entry. The door team focuses more on overall presentation and behaviour than on pushing for a higher age threshold.
Accepted ID at Opium
Opium enforces a Challenge 25 policy in line with UK licensing standards. If you appear to be under 25, the door staff will request photographic ID. The following documents are accepted:
- A valid passport (any nationality, must not be expired)
- A valid UK driving licence (full or provisional)
- A PASS-accredited proof of age card
- A valid EU or EEA national identity card
Opium will not accept university or college student cards, gym memberships, work IDs, expired documents of any kind, or digital copies of ID shown on a phone. Given the venue's location in Chinatown, it receives a large number of international visitors, so foreign passports and EU national ID cards are routinely accepted without issue, as long as they are valid and original.
Age Policy by Night
Opium is unusual in that it operates across multiple formats within the same building. The ground-floor cocktail bars open earlier in the evening, while the upper-floor club spaces come alive later at night. For the cocktail bar sessions, the 18+ minimum applies but the atmosphere is more akin to a sophisticated bar than a nightclub. Later in the evening, as the music picks up and the dancefloor opens, the entry process becomes a little more structured.
On Fridays and Saturdays, Opium is at its busiest, and queues can form outside the discreet entrance. The Opium Guestlist through London Night Guide helps you bypass the main queue and ensures the door team is expecting your arrival. A Opium table booking guarantees your group a dedicated area and priority admission.
Weeknight sessions are more relaxed, and entry is typically straightforward for any guest who meets the 18+ age minimum and presents valid ID. Special events, themed nights, and ticketed parties may occasionally have adjusted entry procedures, so always check the specific event details.
Tips for Getting In
Opium's hidden entrance and intimate atmosphere create a distinctive arrival experience. These tips will help you make the most of it:
- Bring valid photo ID without exception. The door staff will check, and no ID means no entry.
- Know where the entrance is before you arrive. Opium is located above a restaurant on Gerrard Street, and the entrance is easy to miss if you are not looking for it. Arriving confidently shows you know the venue.
- Be courteous with security. The door team at Opium manages a smaller, more intimate space and values guests who are calm and well-mannered.
- Ensure all members of your party meet the entry criteria. At a venue this size, the door team assesses each guest individually.
- Register on the Opium Guestlist through London Night Guide for a smoother, faster entry process. It is free and takes seconds.
Dress Code Reminder
Opium has a smart-casual dress code that matches its upscale cocktail bar atmosphere. Men should wear clean, presentable attire, smart shoes, and avoid sportswear or overly casual items. Women can dress in cocktail wear or smart-casual outfits. The venue appreciates guests who make an effort with their appearance. Trainers, shorts, and sloppy clothing will be refused.
