Maybe you can access the internet, but I am probably too late! I was in Paris weekend 18th to 22nd May just gone. Ubiquitous Kronenbourg 1664 and Heino on tap at €4 for 25cl or €8 fpr 500ml in most touristy areas. Best place for me was Taverne de Cluny, Rue de la Harpe, Latin Quarter, nearest metro Cluny - Sorbonne. Very good bottled range; beer of the month Duvel at €5. They also had a decent French brew (brewed in Belgium for a French brewer) called Oubliette. Pretty tasty. Otherwise stick to the vin!
