When I was in Paris for two months last spring I attended the Franglish sessions. They are held on Sundays and Tuesdays for two hours. You are assigned to a table with a French speaker. You speak one of the languages for seven minutes and then the other for seven minutes. A very nice lady comes to tell you when it is time to switch languages. After the fourteen minutes is up either you or the other person switches tables so you get to talk to several different people in the evening. The cost is ten euros which includes your choice of a cocktail. The events are held in bars; one on rue Oberkampf and the other in a bar around the corner from rue Oberkampf, but I forget the name of the street. It's not really that hectic and you get to meet some really interesting people from all walks of life that you would never meet otherwise. I found the events to be a lot of fun. Of course, you are free to stay after the event and chat with other participants. I will be returning to Paris in a few months, hopefully on a long-stay visa or if not for ninety days, and I will definitely be going to the events again.
