I've been wondering, also, if there are any good suiting tailors that might fall somewhere between the clearly heinous rotknopf (http://rotknopf.at/), and places like Knize and Niedersuesz? I had a very nice telephone conversation the other day with Johanna Kastner, but at EUR 3200 for a two-piece without cloth, still quite up there. I have read some very nice things about Michael Possanner, but can't find any information about pricing (if anyone here has visited him). Any experiences or suggestions?
If anyone is looking for decent alterations tailors, I can recommend Schneider and Maurer (schneiderei-innenstadt.at), but be prepared to wait longer than anticipated.
Also, I've been looking for a half-decent dry-cleaner, and Sylvia's Textilreinigung seems to be the best I've encountered (in 1060 just off Mariahilferstr.)
