Later, wandering around the old town, I found evidence of the Estonian Banksy:
Plus a mention in despatches has to go to the shopping centre on the port.
Ground floor - clothes, cheap booze and general tat.
First floor - clothes and solarium.
Second floor - 'private massage booths'.
Third floor - well, whilst I don't understand Estonian or Russian, I think it's safe to say it was a full-on knocking shop!! Taking a look at the dog-rough women on the ground floor, my surmisal is that it wasn't a particularly classy joint ; )
Still, I'm sure the sailors on shore leave had fun....
