This is a closely kept secret of the many students in the area who attend the Sorbonne. The tiny shop is just two shakes from the Odéon métro and it serves some of the best hot chocolate in town, that is, if you like your hot chocolate stiff and thick. The pastries on offer here to accompany that are the good old-fashioned kind you find in Vienna. So think more along the lines of apples and poppy seeds. A stop here offers something different from the baba au rhums and millefeuilles you find in nearly every other pastry shop here in Paris.
