Le Comptoir by BeatChick
Lo, the shiny brass comptoir! In any bar in Paris it is the cheapest place to get a drink. Go to the bar, order a drink, pay cheaper & drink it there. Prices go a bit higher if you go to a table & even higher on le terrasse, which affords fab people-watching.
This one is located at Tabac le Marly - 252 rue de Rivoli.
