The Rialto: Location and Key Facts
Grosvenor Casino The Rialto is at 3-4 Coventry Street, London W1D 6BL. From Piccadilly Circus it is roughly a three minute walk, and only a little further from Leicester Square. This stretch of the West End is one of the densest entertainment zones in the country.
Licensing for the building sits with Westminster City Council, while overall gambling regulation is handled by the UK Gambling Commission.

The Rialto building used to be a theatre and then a cinema. Grosvenor now markets the venue as a “Theatre of Gaming”. It is a slogan, but the design leans into it: a wide, staged layout with an open view across the room. The atmosphere is less like a low-ceiling basement club and more like a converted auditorium. For a first visit, that detail helps set expectations about how visible and open the space feels.
Food is not served as a buffet line. Instead there is a sit-down restaurant and a bar, both operating inside the casino. Table bookings are handled through OpenTable under the name “Grosvenor Casino London Rialto.” The Backstage Bar works as a separate social area within the same walls, with its own style and its own Instagram handle: @backstagebar_therialto. Dress code through the whole venue is smart casual, not formal but still tidy.
Arriving At The Rialto
General entry for gaming does not need a booking. Walk in, go to reception and show valid photo ID. Passports and driving licences are the usual documents, other government-issued photo ID can also be used. The minimum age is 18 and staff apply that strictly, visual age guess is not enough on its own. No charge is taken at the door for entry.
Once checked in, new visitors can pick up a Grosvenor player card from the desk. That is optional but needed for loyalty offers or tracking play. Gaming tables generally run already, so it is possible to sit straight into blackjack, roulette or electronic machines.
For food, guests either speak to the restaurant team or head over to the Backstage Bar directly and ask about space. Larger groups and private hire do not work as walk-ins: these have to be set up in advance by contacting the venue.

The second address appears because internally the site is sometimes referenced as both “Rialto” and “Piccadilly.” That dual naming can cause a minor search glitch online, but it still refers to the same property.
A small practical tip that applies broadly: when visiting any UK casino for the first time, it is safer to carry two IDs instead of one. Often one document is enough, but if the first has an issue with expiry, legibility or name spelling, the second one avoids a delay or a refusal at the door.
Grosvenor Casinos: Brand And Network
Grosvenor Casinos Limited operates roughly 53 physical casinos across Great Britain. Within that group, The Rialto is positioned as one of the key London venues, alongside Grosvenor Casino The Vic (The Victoria).
All properties run under UK Gambling Commission controls. Each building then has an additional local licence with the relevant council.
| Brand Layer | Entity |
|---|---|
| Venue name | Grosvenor Casino The Rialto |
| Operating company | Grosvenor Casinos Limited |
| Parent group | The Rank Group |
| Online casino platform | grosvenorcasinos.com |
| Online niche brand (2022) | The Rialto (online) |

In 2022, Rank extended both The Rialto and The Vic into separate online-facing labels. These are niche brands that sit under the Grosvenor structure, not standalone operators. The Rialto name appears digitally through rialtocasino.com, but the underlying platform is still Grosvenor.
For UK players, the primary online home is grosvenorcasinos.com, covered by licensing from the UK Gambling Commission (account number 57924) and by the Gibraltar Gambling Commission.
