if you're a bit of a spender
I recommend 40 Westt or Queue de cheval
the only lounge I go to is Whiskey's on Bernard and St-Laurent in Outremont
great staff, very friendly!
Bernard street has a lot of cool places to go to.. most people often dismiss it.
there is also a good restaurant with a great flair bartender called L'Assomoir.
These are obviously a bit higher in budget then what was recommended, but a guaranteed great time.
