Apologies that I can't answer your question specifically (I've never been to Pascha) – I have been to Munich, however, and thought I’d share my experience. Hopefully you find it useful.
When I visited Munich 2 yrs ago, I found it quite difficult to identify a location in advance that would meet my expectations in terms of quality, level of service, vfm etc - certainly compared to other parts of Germany (where I'm originally from). In the end I settled for "Susanne Hahn":http://www.susanne-hahn-muenchen.de/
They are quite a small place (only 3 ladies at any one time, on a weekly rota) but in my experience – admittedly on the evidence of only a single visit – the information on the website is accurate, so you should be able to tell in advance whether or not a visit might be worth it. I visited a lady called Selina who was very good (incl DT & CIM). A was on the menu as an extra, if I remember correctly, but I gave it a pass. Rates are relatively high by German standards, but that is generally true for Munich, as far as I can see. Oh, and the rooms were very nice indeed, should this be important for you.
As an aside, and as noted in another post above, OWO is technically illegal in Bavaria (technically it is an “Ordnungswidrigkeit”, I think). Susanne Hahn even had an official-looking document on the wall as a reminder to guests! Even so, it wasn’t a problem to enjoy these services on the day… Some places seem to use a “code” to indicate what might be available. The SH website for example refers to “Super Spezial Service” (i.e. OWO) and “Total Super Spezial Service” (i.e. CIM). Not sure how general these conventions are, though.
Finally, if you want to look beyond Pascha and Susanne Hahn, you may find this forum useful, which is similar to UKP:http://www.lusthaus.com/
Quesadilla, inspired by your (and Hendrix’) reviews I had several very enjoyable encounters recently, so hopefully with these brief comments I could give a little bit back. Enjoy your trip to Munich!
