London welcomed 20.9 million inbound visitors in 2024, according to GLA Economics’ Tourism in London report, published in February 2026. That figure puts the UK capital broadly in line with its pre-pandemic peak and confirms its position as the most visited city in Europe. But for travellers building a longer itinerary around a European city break, London is only the starting point. The continent offers a string of destinations that go well beyond the obvious. Art, history and architecture draw the crowds. What fewer people plan around, but many end up enjoying, is the casino experience each city has to offer.
A study by WhichBingo, leading experts on slot sites, recently ranked the best casino in each of Europe’s ten most visited cities, using Google review scores as the measure. London came out on top. The rest of the list makes for a compelling argument that wherever your European trip takes you, there is a world-class venue worth at least one evening of your time.
London: Grosvenor Casino, St Giles (4.8)
Set in the heart of London’s theatreland, the Grosvenor Casino at St Giles scored 4.8 out of 5 in Google reviews, making it the top-rated casino venue across all ten cities studied. The gaming floor covers American roulette, blackjack, three-card poker, Punto Banco and Shoot Dice. Its location puts it within easy walking distance of Covent Garden, the West End and a dozen Michelin-listed restaurants, which makes it a natural fit for an evening that starts with theatre or dinner and ends with a few hands at the table.
London drew over 20 million international visitors in 2024, a figure that made it one of the three most visited cities on the planet. Its casino scene has matured to match that status. The Grosvenor group alone operates several central London venues, but St Giles consistently earns the strongest reviews from visitors who want a smart, unpretentious night out rather than the high-pressure atmosphere of a members-only room.
Paris: Club Circus Paris (4.5)
Paris came second in the WhichBingo study, with the Club Circus Paris earning a score of 4.5. The venue sits in the 16th arrondissement, within walking distance of the Parc des Princes and the Roland-Garros stadium. It runs 31 tables across poker and dealer games, with a restaurant and bar on site. For visitors combining a Paris trip with sport or a stay in the south-west of the city, it fits naturally into an itinerary that might otherwise revolve entirely around galleries and bistros.
Paris and London were the two most visited European cities between 2019 and 2023, each recording over 20 million inbound tourist arrivals in 2019 and again in 2023. Both have the density of dining, culture and transport that makes a casino evening easy to fit in without disrupting the rest of a short break.
Vienna: Casino Baden (4.4)
Third place went to Vienna, or more precisely to Casino Baden, which sits just outside the city in the spa town of the same name and scored 4.4. Described as one of the largest and most architecturally protected casinos in Europe, it is a genuinely historic building as well as a functioning venue. The combination of thermal baths, the Vienna Woods and a grand casino makes Baden a logical day trip from the city, and one that tends to leave a more lasting impression than a third afternoon in the Kunsthistorisches Museum.
Madrid, Amsterdam and Beyond
Madrid’s Casino Gran Via I Poker Room ranked fourth with a score of 4.2. It occupies a classical building on one of the capital’s great boulevards, giving it an architectural appeal that matches the grandeur of the street outside. Amsterdam’s Holland Casino came fifth at 4.1, its modern interior a deliberate contrast to the city’s canal-house aesthetic.
Barcelona and Rome were tied in sixth place, both scoring 4.0. The Casino Barcelona sits near the seafront, making it a workable stop on a trip that has already covered the Sagrada Familia and Las Ramblas. Rome’s Slot Palace Le Palme offers a different experience entirely, a lower-key gaming room in a city where the main sights tend to dominate every waking hour.
At the lower end of the study, Athens registered 3.9 with the Regency Casino Mont Parnes, a venue that requires a short drive out of the city centre but rewards visitors with views over the surrounding hills. Milan’s Casino di Campione matched that score, while Venice’s Casino di Venezia brought up the rear at 3.8, despite occupying one of the most remarkable buildings of any casino in the world, a 15th-century palazzo on the Grand Canal.
Planning a Casino Evening Into a City Break
For most travellers, a casino visit works best as one component of a broader evening rather than a standalone destination. Every venue in the WhichBingo ranking has a restaurant or nearby dining, and all are accessible from the central tourist areas of their respective cities. Dress codes vary but are generally smart casual at the venues reviewed, with the exception of Casino Baden, which leans toward formal.
The spread of review scores across these ten cities is tighter than it might appear. The gap between London at 4.8 and Venice at 3.8 is a single point, which suggests the quality floor for casino venues in Europe’s major cities is reasonably high. Visitors who are already exploring European destinations for a city break are unlikely to be disappointed by the gaming options, regardless of which capital they end up in.
What the rankings do confirm is that London’s casino scene currently sits at the top of the European hierarchy, at least by the measure of visitor satisfaction. For a city that is also topping global search trends for travel in 2026, that is one more reason to put it at the front of the shortlist.
