Down the hill from Sacre Couer in Montmartre is this very silly and un-sacred fondue joint.  They famously serve their wine in baby bottles, no glasses at all.  You are at a communal table which you have to climb over if you happen to be seated against the wall.   A prix fixe includes some greasy amuses, fondue, a baby bottle filled with table wine and dessert.  You get to keep the bottle as a memento.  Students throng the place.  LG
