Absolutely the finest Taiwanese cuisine! My hosts ordered the food so in many cases I have no idea what the courses were - just that each one was more delicious than the last! The service was constant, unobtrusive and slightly abrupt in that Asian way that westerners mistake for ill-temper when it's really about efficiency. Dark interior ambience suggesting wealth and privacy. There are separate dining rooms for private parties as well. It wasn't until I visited the toilet that I realised how many people the restaurant can accommodate. Very clever interior design. If you're in Taipei, and you want high class dining - come to Ao Ba. It's not crazy expensive either - well compared to the brilliant meals you can get on every street in the city.
