In Montreal

1) Would be a supper-club

2) Close enough to what we would call an after hours ; opens towards midnight closes at noon. Little to no alcohol, drugs readily available on premises, or pop yours before getting in. Typically has a techno area and a hip-hop area.

3 ) Club / Night Club here would be as @scraft describes in his reply.

4 ) @scraft > "Places you sit down at tables and drink are typically pubs or bars. These days the two are pretty similar, at a push the more traditional feeling places are more likely to being pubs." Same over here. Note the price discrepency with what OP describes in 1) and what this quote refers to ; beer, shooters, 100$ bottle of non-descript "booze".

[Edit] I might as well add 5 ) our world renowned strip-clubs. High-end no touching - down to sex on premises available. Stuff in between and probably ways to leave with a girl at any joint if you're nice, polite and pack $.

Disclaimer ; Intel valid as of 10-15 years ago ... probably much the same.
