Qwest? The Aussie bar....
ベルファーレ: The techno club?
Everyone should try any bar in Roppongi (like Mamy said).
My recommendations:
六本木:Hobgoblin, Legends, Paddy Foley's, Gas Panic, 911, Heartland
麻布十番: Blarney Stone
広尾:Bonds
目黒:The Tavern, The Black Lion (Little Euro)
恵比寿:What the Dickens
神谷町:Mulligans
There are always a lot of foreigners at these bars to practice your English.
