The pan-Asian restaurant at the Anantara Resort & Spa is straight out of a spy movie, with waitstaff in 1920s garb, menus delivered in 'top secret' envelopes and interior decor resembling the offices of MI6. It's appropriate, considering that the gorgeous teak villa housing the restaurant used to be the British Consulate. Ask to see the secret room behind the false bookcase.
The food's top-notch, though some dishes have the spice dialled down to appeal to international palates. The hotel also has an international restaurant in a similarly romantic location overlooking the river.
