This resplendent five-star hotel, in a terrace of beautifully restored Georgian townhouses, opened in 1988 but looks like it's been around a lot longer. Try to get a room in the old house (with the largest private art collection in the city), rather than the newer wing, to sample its truly elegant comforts.
Located opposite Government Buildings, its marble corridors are patronised by politicos, visiting dignitaries and the odd celeb. Even if you don't stay, book a table for the superb Art Afternoon Tea (€55 per person), with endless cups of tea served out of silver pots by a raging fire.
