There's a new cocktail bar in Taipei, started by a friend of mine.
Here's a review http://theboolion.wordpress.com/2012/11/04/ounce-the-world-class-cocktail-bar-comes-to-taipei/ (not mine).
It is actually two parts: a cafe in the front with gourmet chocolate and premium coffee,
and a cocktail bar /speakeasy in the back with custom, well-crafted drinks.
I haven't been to the cafe yet myself, as i'm in the USA currently, but I've seen the amount of work put into the design, the menu, the staff training, the philosophy, and I'm sure you won't be disappointed. Website: http://ouncetaipei.com/
PS it's not just for drinkers. The cafe in the front has really good chocolate and coffee, imported from NYC.
The back is more for drinkers These aren't normal cocktails.. they're more works of art
finally one of their creeds is to not be pretentious and make everyone feel welcome. So don't think like this is an uppity place, because it's not. (or shouldn't be)
