The l'Oisive Thé is like a little slice of home away from home for Anglophone knitters, like me, living in the big city of lights. From the buttery scones to the cream-cheese frosted carrot cake, to the best chocolate chip cookies served in Paris, to the loveliest stock of American yarn available within the city limits, it really has everything a homesick knitter could ask for.
I'm a regular at Wednesday night tricothé, and find the evening perfectly placed to split a busy and often hectic work-week in the urban bustle. The shop is located in one of my favorite Parisian arrondissements (home to Paris' Chinatown, Parc de Choisy and the village-esque Buttes-aux-Cailles), so I try to go there any chance I get!
For anyone looking for hard-to-come-by-in-Europe American yarns, this is the place to go. I'd suggest coming by on the weekday, because, as was mentioned in other comments, the weekends can be hectic because brunch is crazy popular here (and rightly-so...both price and quality are excellent for Paris). Wednesday nights are lots of fun, too, so much that they can get pretty packed (knitting is starting to FINALLY make a comeback in Paris), so come early!
