This is a lovely, off the beaten path salon du thé! Rosa Bonheur is just so cute, quaint, and charming that you just want to pass the day away enjoying the coziness of it! It's a bit odd, in a good way, though... lots of character- definitely MY type of place!
"The attractions of the Parc des Buttes Chaumont are numerous. The park includes several cliffs and bridges, a grotto that encloses a 20-meter high waterfall, a lake, and several English and Chinese gardens." Wikipedia
