6.4_B: Don't know which Abacus speakers you might have in mind - have a link to a pic, maybe? Generally they have nice stuff, though.
And yup, "Das Gollier" was pretty nice - and I remember it to also have had a good choice of vegetarian food. I haven't been there all that often, though - the Schwanthalerhöhe never really was "my area", as finding a parking lot there has always been rather problematic. And in the meantime it doesn't exist anymore anyway, at least as far as I'm aware.
But there has been a lot of change anyway during the last 10 to 20 years. Hardly any of my favourite bars, cafés and restaurants I used to visit in the 80s and 90s still exist - and also quite a few of my favourite shops (including hifi shops). And I don't know, whether you've also been to our "electronic mile", the Schillerstraße (and area around), when you were here, but that has also changed pretty considerably. And then we've also got quite a few new tunnels in the southern to western part of the Mittlerer Ring, where you've got to drive carefully, as they have installed quite a few speed traps/cams...
Greetings from Munich!
