In Lyon, there is a Bewelcome meeting every Thursday in the bar "l'envers des pentes" 112, Montee de la Grande Cote 69001 Lyon It starts at 8 pm or 8:30 pm. You can check there : http://www.bewelcome.org/groups/842 Bewelcome is a non profit hospitality network. You can join these parties even if you are not a BW member.
Whatever the day of the week, you can also ask a Bewelcome member for hospitality, or some may be able to show you around etc.
The atmosphere is very good, everybody can speak english and exchange with foreign people (and some speak as well other languages) but if you prefer to practice your french, that's possible too ;).
At some moment in these evenings, there is a special activity (music, short movies, improvisation workshop, prestation of a special travel, etc.), the reste of the time being dedicated to free exchanges between dynamic people open to various cultures.
Be welcome ! ;)
