For all those who ask for numbers of SP's at NL, you do not need ant number of any SP to go there. Here is a guide which I hope will answer a lot of queries.
There are 2 buildings at NL. The 1st is opp. a flour mill in the lane and the 2nd is further ahead after one building in between. The lane itself is opp gate no. 6 of Sir HN Reliance Hosp. Both buildings have 3 flats each.
Kancha's place is on the 2nd floor of the 2nd building. He's almost always available. In case he is not then the other SP's k@mlesh, mithil@esh, Um@sh, Pr@m etc. will attend to you. The rates over here are 2.5K and 3.5K. The flat B1 F1 is also under the same management and one of the SP's from kancha's will take you over there. The rates over there are 3.5K, 5.5K and sometimes there are girls for 11K. In case you go straight to B1 F1, the you can look up SP Kr@shna.
Below Kancha's at B2 F1 the rates are 2.2K and 3.5K. The SP's are R@ju, R@mu etc. I have never been to the flat on the ground floor.
At B1 F2, I deal with SP Chh@tu. Here the rates are 2.5K and 3.5K.
At all the places, the rates are fixed and they usually don't cheat on the rates. One can have a look at all there is to offer, interview girls to check services offered and if nothing found suitable then walk out and check the other flats. There is absolutely no compulsion to take someone. The SP's don't harass you if you don't find someone suitable. You can even ask the SP to suggest someone if you require a specific service. Safety is usually not an issue as they seem to have a good equation with LE and seem to get information of any impending problem. The best time to go there is 5:30 pm onwards.
Hope this answers most queries of those who want to go there but are hesitant.
