Canton Blue

Verdict: Worth booking, but plan two visits to get the most from it

Getting a table at Canton Blue takes effort. The restaurant sits inside The Peninsula London at Grosvenor Place, one of the city's most in-demand hotel dining destinations, demand runs well ahead of availability most evenings. Book at least three to four weeks out for dinner, longer for weekend slots. If you are flexible on timing, a weekday lunch is your leading entry point: the room is quieter, dim sum is the obvious focus, you will leave with a clearer sense of whether the full dinner experience is worth returning for. It is. Plan two visits minimum to do the menu justice.

What Canton Blue is

Canton Blue is a Cantonese restaurant operating at the top of London's price bracket, holding a Michelin Plate in both 2024 and 2025. That recognition signals consistent, competent cooking rather than the fireworks of a starred kitchen, which is an accurate description of the offer: this is a restaurant built around authentic Cantonese technique and a wide-ranging menu, not a tasting-menu-only format. It has its own entrance on the side of The Peninsula building, which means you can arrive and leave independently of the hotel lobby. Before or after dinner, the adjacent cocktail bar Little Blue is worth factoring into your evening.

For a first visit, the structure of the menu can feel broad to the point of being difficult to navigate. The menu covers dim sum, roast dishes including Peking duck for two, a fuller Cantonese selection beyond those anchors. The wine list includes Chinese rice wines by the glass, which is worth noting if you want to explore pairings beyond a standard European list. On a first visit, orient around two or three dim sum dishes and the Peking duck. That combination covers the kitchen's range without overextending the bill.

Multi-visit strategy

If you are serious about Cantonese cooking at this level, Canton Blue rewards a structured approach across two or three visits rather than trying to cover everything in one sitting. First visit: arrive early in the evening, eat at the main dining room, order dim sum and the Peking duck, spend time at Little Blue before or after. This gives you the full arc of the Canton Blue experience and the measure of the cocktail bar, which is a genuine asset rather than a hotel afterthought.

Second visit: work deeper into the à la carte menu beyond the obvious roast dishes. The extensive selection means there is meaningful ground to cover in the broader Cantonese categories. A weekday lunch for a second visit makes sense on budget grounds: the setting is the same, the kitchen is the same, the bill will be lower than an equivalent dinner. For comparison, London's Cantonese offer at lower price points includes Dim Sum Duck and Gold Mine, both of which are worth knowing if you want the cuisine without the ££££ commitment. Canton Blue's advantage over those options is not just the cooking: it is the room, the cocktail bar, the overall occasion.

For a third visit, if you have the appetite for it, the wine and rice wine list is worth giving proper attention. The Chinese rice wines by the glass represent something genuinely unusual for London, pairing them alongside a focused Cantonese selection is a different experience from the first two visits.

How Canton Blue sits in the broader picture

The Michelin Plate (2024 and 2025) places Canton Blue in a tier below the starred Cantonese kitchens you would find in Hong Kong or, closer to home, the level of Chef Tam's Seasons in Macau or 102 House in Shanghai. In London's current Cantonese market, it sits at the formal, occasion-led end of the category. If you are travelling from elsewhere for Cantonese cooking specifically, the honest position is that Canton Blue is not London's only answer, but it is the most complete occasion-dining version of the cuisine in the city. The combination of the Peninsula setting, Little Blue, the Cantonese menu in a room built for a long evening is not replicated elsewhere in London.

For context on London's broader fine dining picture, our full London restaurants guide covers the category in detail. If you are building a wider trip, the London hotels guide, bars guide, and experiences guide are also useful starting points. Outside London, the UK's destination Cantonese offer is thinner at this level, though the broader fine dining circuit includes venues like Waterside Inn in Bray, L'Enclume in Cartmel, Moor Hall in Aughton, Gidleigh Park in Chagford, Hand and Flowers in Marlow, and hide and fox in Saltwood for different occasions and cuisines worth considering on a broader UK trip.

Practical details

Reservations: Book three to four weeks ahead for dinner; weekday lunch is easier to secure. Dress: Smart; The Peninsula hotel standard applies and the room expects it. Budget: ££££ — position yourself at the top of London's restaurant price bracket. Getting there: The restaurant has its own entrance at the side of The Peninsula, 1 Grosvenor Place, SW1X 7HJ; Hyde Park Corner is the nearest Underground station. Groups: Suitable for small groups; contact the restaurant directly for larger party arrangements. Dietary needs: Given the breadth of the Cantonese menu, the kitchen is well-placed to accommodate most dietary requirements, but flag specifics at the time of booking rather than on arrival.

For a ££££ venue in a five-star hotel, that is a signal worth registering: the Michelin Plate recognition sits alongside a customer score that reflects mixed experiences at the price point. Read the reviews before booking and cross-reference against your own priorities: the setting and occasion score consistently well; value for money divides opinion.
