The BRASS MONKEY-XINYI
The Brass Monkey is an Antipodean-style sports bar that really does boast something for everyone. They've got great screens and sound, and are thusly packed for any major sporting event (you can check out the World Cup pics on their website), and that's always a plus.
Brass Monkey is also your spot for fallback plans on New Year's Eve, Halloween, Saint Patrick's Day, etc. There are also Ladies Nights, remarkable even among Ladies Nights, and a Taipei institution for some time now. Great music, free drinks and cheap shots - everyone wins.
Other nights include Salsa Tuesdays and Pub Quizzes on Wednesdays. The rest of the week this is a great spot for some relaxed beers and conversation- even a meal.
