There's not a whole lot to chose from downtown. You may want to try 490A Yonge street. It's not the cleanest place in the world, but many of girls are very hot (especially Jessica). While the mileage may vary slightly depending on the girl and her relationship with the client, it is all within normal MP limits. You may want to check out a new place called Embodyment, which is a block north of 490A (I think 518 Yonge). It looks clean and new, but the reveiws have been mixed.
If you're looking for better mileage downtown, you may want to check out Oasis or Friends on the escort section of this board.
Good luck and I hope you'll share your experiences.
