Yes, worked there - off and on... Partnered with a new adult biz in Prague just after the "revolution". It was like giving candy to kids at Christmas time - amazing volume of business
My partner made so much money he diversified into reconstuction and played a role in revamping the Opera House - which was already an impressive building.
Never been there for a while now, but hope it has not been screwed by stupid western culture - and hope they have retained the bullet-holed walls for history (where the Nazi's shot people in the streets).
