You can also check out this site for places in Germany, which might be easier to get to:

A user on another forum that gets attachments and great cuts goes to a place called:
Salon Gisela Zöhner
He said the website isn't that informative but he's consistently had very good cut-ins there and they're very reasonably priced.

This is his email address (which he gave out) if you want to contact him directly to discuss where he goes to.
