I visited this place about one month ago, so I am not sure whether it is still open. You can check by phoning 0113 131974. Address 290/3/1 High Level Road, Kirulapone, Colombo 6. It is just past Odel if you are travelling from Colombo. There is a prominent board at the entrance. You go up the stairs to the MP.
The girl I got was a 6 in looks, age about 26, fairly slim. I have forgotten her name, but she said she normally works at the Boralesgamuwa branch. She provided good extras and did not demand a particular amount as a tip. I gave her Rs. 1000 because I was satisfied with her service.
I am not sure how safe this place is because it is very visible from the main road.
