I believe i had once started a similiar thread here.
Here are the ones i go to in the west and have been quite successful.
On The Curve........by square one, missisauga Fri/Sat
Blue Suedes(now called Honolulu Lulu's)..........just off hurontario just past 403 i forget the name of street Fri/Sat.
Twisters.................queen st, brampton Fri/Sat
Club54..................harvester rd, burlington Fri/ Sunday
My Apartment........hurontario just north of 401 Fri/Sat
Mermaids(Valhalla Inn).....East Mall south of burnhamthorpe, etobicoke. Fri/Sat.
My personal favorite is On The Curve, Blue Suede(Now called Honolulu Lulu's) and Club 54.
If you want easy chick and don't care about looks too much Try Twisters and Mermaids..........horny married,divorced cougars.
These are all 25 and older crowd bars. So lots of cougars.
