266 Adelaide Street West (dead next door to the firestation), 3rd floor. The Beatles memorabalia shop is on the ground floor, the second floor is currently vacant. Not completely discrete, but I've seen worse setups.
No website. $40 door fee for half an hour. One shower at the end of the hall. The girls generally do a good job of making sure customers don't bump into each other.
Used to be a regular favorite of mine when Linda was there. If you do go, try to get Tracy. New girls aren't much in the way of eye candy, but good at what they do.
