This was a great bar right off Old Town Square. There was no cover, and the drinks were not too expensive (this is Prague, remember). One thing that was nice about Marquis was that in addition to their long bar, there were a few other places to sit with your friends. There were many TV monitors, and I distinctly remember them showing a lot of Fashion TV, which I have not seen much at all in the U.S.
The place was rather dark, but I felt had a good atmosphere. You could either order drinks directly from the bar or from waitresses. This was strictly a bar with no dance floor.
