This was my favorite bar in all of Tallinn, and I did an extensive survey. The reason I liked it was because it was just so surreal--an Egyptian themed bar in the middle of Estonia. Very, very strange. But cool! Plus, they had sheesha. I hadn't had sheesha in a loooong time!
We stumbled onto this by accident on my last night in Tallinn, lured in by the pyramids in the sign. The decor is pure Egyptian kitsch and the drinks are a bit overpriced, but this bar was one of the few that wasn't full of tourists. The music was typical European techno and the crowd seemed to be young, professional Estonians out for the night.
One of the Egyptian gimmicks at Mumia is the availibility of Nargileh or Sheesha smoking from large hookahs. Being a sheesha fiend, I had to order some for my table! The reaction from the Estonian clientele was priceless and I very quickly realized that most people had not seen the hookahs in actual use. I believe we started a trend, as a few tables followed our lead and soon the whole bar was smoking apple-flavored tobacco and a good time was had by all.
