I'm not being critical, well I suppose I am, but I'm getting reading about l'Ami Jean-related posts boredom syndrome.
I feel there was a time when Chowhound was mainly concerned with more humble fair - Chinatown vendors of a riff on the steamed dumpling, or slavic street peddlers of variations on the meat or vegetable, or meat AND vegetable, encased in pastry concept.
Anyway, in these cash-strapped times, I propose to get back to the spirit of Chowhound's founding-fathers with this economic downturn friendly question: Where do you get the best street crepe in Paris? Not your posh pre credit-crunch sit-down creperie crepe. I mean an on your uppers, everything's going to ruins crepe that can you buy, and eat, in the street. Savoury. Sweet.
I recommend a guy who has a stand outside of a café the south side of the rue de la Verrerie, I think between rue des archives, and rue du temple (sorry I can't be more precise, but if it helps he has a beard...and wears jeans...). He does a very good cheese and mushroom number, where he uses good gruyère, freshly sliced mushrooms as opposed to the habitual canned ones, and a ton of freshly ground pepper. Costs 3 euros 50.
