I recommend you order two plates. Well, it's tourists prices. If you intend to travel to Paris for folkdancing, cancel the trip and stay whereever you are, because folk dancing in Paris is a cultural activity confined in it's narrowest aspect to each ethnic group. They dance their national dances as part of their heritage. Forget about writing letters, faxing, and phoning to all the addresses in the folk dance guide books.
Replies are scarce and of no value.
None of the cultural and ethnic organization I contacted via Internet, fax, e-mail, phone have any folk dancing. They hope to have it. By exploring the Internet, however, I made contact with some one who knew some one, whose sister's friend's daughter folk dances. So if you travel to Paris for whatever reason and like to folk dance, then let me take you by the hand and let's go. This is the only place in Paris where they dance international dances.
