To give some insight on some of the places you have mentioned:
Kultfabrik: used to have an über 30 party, now its somewhere else (don't remember where now)
089: too young and a hit or miss door policy for non regulars, the music is also pretty much the same every week
Baby: might be percieved as a bit young, but drinks are expensive and its mostly a place to be seen in than dance in
Pacha: actually is worth a try since international DJ's do come through on a regular basis, but as everything depends on the night you go.
Max & Moritz: yep, young, next
Milch Bar: more youngins but a better mix of music than 089 and the partying goes till really really late (or early, depends of how you think of it)
Harry Klein: mostly house/electro, pretty similar to
Rote Sonne (near
Pacha and 089), mixed crowd but no commerical music to be heard there
Some picks off the top of my head:
Holleschek (sp?) parties are on about every other month and gets a very mixed crowd of people with mostly commerical music. The last one was a couple weeks ago on Maximillianstr. and seems to garner a lot of attention when it is on.
Contrary to belief, if you are looking for just dancing on a Sat night,
P1 is quite on board with the commerical music but quite expensive with drinks and "might" have a hard door entry policy
Thursday nights in Munich are pretty good with the afterwork party at
Pacha & 089. The two clubs are connected with commerical music all night long and a mix of people of all ages.
There is a back on the scene club (thanks siskebap) near
Hauptbahnhof,
Meinburk that seems to be quite older in partygoers but the music might not be commercial all night (I believe there is a cover there).
edmoses is pretty good with attracting a nice crowd of people at their first Saturday of the month hip-hop party, but better get there early since its jammers all night.
Erste Liga has a pretty decent commerical/hip-hop night on Friday nights with a not too young crowd.
That is all I can think of at the moment, maybe something else will come to mind. Enjoy!
