Depends on what you are looking for. I've been to bachelor parties at Misty's and lots of places in the GTA.
Misty's: girls are hot but very little contact. The place is a stage and a semi-private area. Barrie just isn't the same as the GTA.
GTA: lot's places with hot girls. lot's that also offer more contact. Some have showers or bring the unlucky groom up on the stage.
Niagara: Sundowner is highly recommended for bachelor parties.
They will give you the attention as long as you are willing to continue to pay.
You might also try getting a hotel room, tub of beer and calling some local SP's to strip for a few hours.
