I had 3 nights at the ANA Intercontinental. It was a good experience, but nothing remarkable.
The rooms were comfortable if a little pedestrian in their décor. The restaurants were excellent and in common with Tokyo, ridiculously expensive
Breakfast in the atrium was fine – the buffet was good and varied and the service was acceptable given the volume of guests.
It is a good business hotel, centrally located and with pleasant and professional staff.
