Arguably the most famous hotel in the city, Mandarin Oriental Bangkok offers a traditionally charming experience. Located on the banks of the Chao Phraya River, there are 393 rooms, including the Garden Wing’s 35 atmospheric suites. Eight restaurants offer a range of cuisine from French at Le Normandie to Thai at Sala Rim Naam. Cross the river to visit the cookery school, gym and excellent spa, which is home to 15 treatment rooms and an Ayurvedic penthouse. Service is outstanding.
