You said before you were looking for wine shops in Münich.
Well, I know a good place, close to
Odeonsplatz. Had a great time there when my Hungarian friends were visiting - all wine lovers, by the way, just like myself! :-)
(Suffering here among all these beer drinkers.)
Don't know the name of the place, but I can tell you precisely where it is: walk on Ludwigstrasse towards that monument in the middle of the walking street, monument called "Feldherrnhalle", one church is up on your right side, called Theatinerkirche. You can't miss it. So, there you stand... and one entrance to Hofgarten is at your right.
There you stop and look to the right. There is a lovely little wineshop there, was very crowded, even during Octoberfest. It is like a little Hofbraähaus, also quite noisy...
Have fun, and good luck with the business!
