77 London — also written Seventy Seven — is a 550-capacity electronic music club in the basement of The BoTree hotel on Welbeck Street, Marylebone. It was designed by Concrete, the Amsterdam studio, as a deliberately asymmetrical room lit by synchronised gold and silver LED, and it is one of the few rooms in this part of London booking dance music seriously.
We book central London every week, so here is a straight read on who this suits.
The Design Actually Matters Here
Most club interiors are decoration. This one is structural. Concrete built an asymmetrical, split-level room: a sunken floor with a mezzanine of booths looking down over it, lit by gold and silver LED that moves with the music. The effect is that the room reads as one space rather than a dance floor plus a seating area — you are never watching the night from outside it.
The Booking Policy
This is a genuine electronic room, not a Mayfair club playing house. Dimitri from Paris and Novak & Vidojean give you the measure of it, and the fact that bigger nights sell through Resident Advisor rather than a guestlist app tells you what kind of crowd it attracts. People come for who is playing.
Being Under a Hotel
More of an advantage than it sounds. Dinner upstairs at The BoTree, down to the club, and rooms above if it runs long — the whole night at one address, with a discreet arrival rather than a street queue. For a birthday or a group weekend that is genuinely useful.
The Crowd
Older than a student room, younger than Mayfair, and dressed smart rather than formal. At 550 it is big enough to have atmosphere and small enough not to feel anonymous — a difficult balance that most rooms this size miss.
What to Know Before You Go
The door moves with the booking. A resident Thursday and a headline Saturday are different nights at different prices, so check before you plan around a figure. And the 18+ policy is worth knowing — some listings wrongly say 21+, which puts people off a venue that would actually take their group.
Is a Table Worth It?
Here, more than most. The mezzanine booths are the best position in the room rather than a corner you have been moved to, so a £1,000 table buys a better view of the night, not a worse one. At eight people that is £125 each, returned as drinks.
The Verdict
One of the few rooms in central London taking electronic music seriously at this scale, in a space that was properly designed rather than decorated. Go for the booking, take a mezzanine booth if the group is six or more, and eat upstairs first.
