Mandarin Oriental, Bangkok Review

The address is Oriental Avenue in Bang Rak, a lane off Charoen Krung Road that ends at the river, and the hotel is three buildings around a garden: the Authors' Wing, which is the original hotel; the Garden Wing; and the River Wing, the tower where most of the 331 rooms are, including ours. Arrival still comes with a jasmine garland, and the lobby beyond it is the hotel's great room — high and cool, open to the river, with the Lobby Lounge at its heart and the Oriental Arcade of shops off it. One thing to know before you arrive: the 150th-anniversary renovation. In April 2025 the hotel announced a programme covering the Authors' and Garden Wing rooms (interiors by Jeffrey Wilkes), Le Normandie, Lord Jim's, The China House, Baan Phraya and the fitness centre, with completion expected by the end of 2025. By our stay the fitness centre was new and Le Normandie had reopened under Anne-Sophie Pic; the renovated wing rooms we did not see.

The category to know at this hotel is the Deluxe Balcony Room: 37 square metres in the River Wing plus a 6 square metre covered balcony with seating. Inside, a king bed, floor-to-ceiling windows, wooden floors and the hotel's nature-patterned rugs, a bath and a separate rain shower, and the standard kit of a Nespresso machine, a Bose speaker and 24-hour butler service. The hotel sells it as poolside or river view; ours, high in the tower, looked straight across the river to ICONSIAM and the Thonburi bank, with the hotel's boats coming and going below. Two things to know. Thirty-seven square metres is compact by the standard of the newer river hotels, and there is a sofa corner rather than a living room — if you want to spread out, the Mandarin Room adds a proper seating area and a dining table, and the suites start at 83 square metres with the Chao Phraya Suite. And the balcony is the reason to choose this category over the Deluxe Premier Room, which is larger inside at 43 square metres but has no outside space: a river you can sit above in the evening, with the boats and the light, is most of what you came for. Ask for a high floor. The old courtesies survive: fruit and a welcome note on arrival, and a printed newspaper each morning.

Marble throughout, a full bath and a separate rain shower, robes and slippers. It is proportionate to a 37 square metre room rather than a showpiece, and in three nights nothing about it needed mentioning to anyone — which, in a hotel of this age, is its own compliment.

The hotel's teak boats are the single best thing about staying here, and they are free. One shuttle runs to ICONSIAM on the opposite bank every half hour from 10am to 10pm — a few minutes across, and you are in the mall and on its riverfront. Another crosses to the hotel's own compound on the Thonburi side, where the Oriental Spa, the fitness centre and Sala Rim Naam are. Take a crossing after dark at least once. The river at night, with the towers lit on both banks, is the view the room is charging you for, and from the water it is better.

Breakfast is at The Verandah, the all-day restaurant on the river with tables inside and out on the terrace: à la carte from 6am, the buffet from 7am to 10:30 on weekdays and to 11 at the weekend. The egg menu is the thing to order from. The Oriental Egg — a crispy croffle, poached egg, smoked salmon, smashed avocado, avruga caviar and hollandaise — is the house dish, and there is a full vegan breakfast menu alongside it, tofu scramble to congee. Ask for the terrace. On the Sunday a clown worked the tables for the children, which tells you the hotel still thinks of itself as a family house as much as a grande dame. We also had lunch here on the day we arrived, from the all-day menu that runs from 10:30am to midnight — Thai classics and Western plates — and it is the right place for a first afternoon by the river.

Dinner was on The Verandah's terrace too. In the rainy season that is the river-terrace option: Ciao Terrazza, the alfresco Italian, and the Riverside Terrace barbecue both close for the wet months. When we checked in late September the hotel listed them shut until 22 October and 24 November 2026 respectively, so confirm before you promise anyone dinner on the water in the rainy season. After 6:30pm the dress code tightens across the restaurants: long trousers and closed shoes for men. The full list runs to twelve restaurants and bars. Anne-Sophie Pic at Le Normandie, on the fifth floor facing the river, reopened under the most Michelin-starred woman chef in the world and holds two stars in the 2026 guide, Wednesday to Sunday only. The China House by Chef Fei does Chaoshan and Cantonese cooking, Baan Phraya serves Thai in a historic riverside house, Lord Jim's is the buffet of seafood and prime cuts, and Terrace Rim Naam is the Thai terrace across the river. We did not eat at Le Normandie this time; it is the obvious reason to come back. After dinner the hotel keeps two old habits going side by side on the lobby level: The Bamboo Bar, Bangkok's first jazz bar, with live music every night, and La Casa del Habano, the Cuban cigar lounge next door with its own terrace on the river.

The spa is not in the hotel. It is across the river in the hotel's own compound on the Thonburi bank, reached by boat, and the crossing is part of the treatment. The Oriental Spa occupies a traditional Thai residence with 18 treatment rooms, the menu drawing on Thai healing, traditional Chinese medicine and contemporary therapies, open from 10am to 8pm. The changing rooms, the sauna and the relaxation areas are on the same side. So is the Fitness & Wellness Centre, and this was the surprise of the stay. It was on the 2025 renovation list and it shows: a new gym with a full Technogym floor — cardio facing a bamboo garden, a strength area with a rack and free weights, a track marked down the floor. Add a yoga studio, tennis and a schedule of classes, all open from 6am to 10pm. It is a proper gym rather than a token one, which is not what you expect from a 150-year-old hotel. The outdoor pool, by contrast, is back at the main hotel, open 6am to 8pm. We gave the compound a Sunday morning: boat over, the gym and the spa's facilities, boat back.

Sala Rim Naam is the hotel's Thai restaurant, in a pavilion on the opposite bank in the same compound as the spa, and it is the one to book for a first night in Thailand. The set dinner starts at 7pm — four courses at THB 2,800 a head or five at 3,400, before service and tax — with classical Thai dance in the room at 7:30 and 9:30, Wednesday to Sunday. The dress code is smart, long trousers and closed shoes for men, and the hotel boat takes you across and back. We looked in on the spa morning rather than dined; it is on the list for the next visit.

The reason the hotel is famous is the low white building at the back of the garden: the Authors' Wing, the original Oriental Hotel, where Conrad, Maugham and Coward stayed and whose ground floor is now The Authors' Lounge. Afternoon tea is served there daily from noon to 6pm: finger sandwiches, pastries, scones and the hotel's own jams, among the wicker furniture, the hand-painted fabrics and the photographs of the writers. Four private lounges open off it for a small party. The dress code applies here too, children included. The hotel calls it one of the most photographed rooms in Thailand and, for once, the claim is fair. The Ambassador Two-Bedroom Suite, with its private glass conservatory, is in this building, reached by private elevator; the 306 square metre Royal Suite is the hotel's other historic suite. The Author's Suites themselves — 101 square metres, named and decorated for the writers — are in the River Wing, not in the heritage building the name suggests. We took tea on the last afternoon, and it is the memory of the stay that has lasted.

Service at the Oriental is correct, polite and everywhere — butlers on call around the clock, as advertised, and nothing we asked for went wrong. What it was not, in three nights, was personal. Nobody used our names unprompted, nobody carried a preference from one morning to the next. It is the service of a very large, very good hotel, and at this rate that is the gap between good and great. The explanation is scale, and it is worth putting numbers on it, because the rate does not tell you. Mandarin Oriental has 331 rooms. Four Seasons, a short way downriver, has 299 — and on our stay there in February 2026 it still felt personal, so scale is not a complete excuse. But Capella, on the same estate as Four Seasons, has 101. Aman Nai Lert, in the city, has 52 suites. The Siam, upriver in Dusit, has 39. At similar rates, a house that small has a structural advantage in knowing who you are, and the Oriental is competing against it with three to eight times the rooms and a century and a half of ritual. The ritual wins on the Authors' Lounge and the river; the small houses win on recognition. Decide which you are paying for.

Mandarin Oriental, Bangkok is still the classic, and it deserves one stay from anyone who cares about hotels: the river and the boats, the Authors' Lounge, a spa you reach by water, and now a renovated fitness centre that newer hotels would be pleased to have. The entry categories are compact, the balcony category is the one to buy, and the service is polite rather than personal — the cost of 331 rooms. The value holds: in our bookings, the entry rooms here regularly open below the equivalent room at Capella, Four Seasons and Aman Nai Lert for the same dates. Perfect for: First-time Bangkok, anyone who wants the river and the history in one address, afternoon-tea romantics, gym-goers, and a first or last night before a beach Skip if: You want to be recognised by name by the second morning, or you would rather have a bigger room than a balcony Book the: Deluxe Balcony Room on a high floor for the river; the Mandarin Room or a suite if you need space; and Sala Rim Naam for the first night. Give us the dates first — we book Mandarin Oriental at the same rate you would pay direct, with our partner benefits added.
