Eva - La Maison Stohrer is one of the best "pâtisseries" of Paris.
Unfortunately, it has no tables and chairs. That's why I advice we going next time to Dalloyau or Ladurée which have tearooms, and where pastries are also wonderful.Btw, Ladurée is not far from Fouquet's.
A little bit of history : When the princess of Poland, Maria Leczinska came to France to marry the King Louis XV, she asked her father King Stanislas, to take Mr Stohrer, court "patissier" to Paris. Few years later, he created his business, still in the family today.
Stohrer has created Baba au Rhum and some think you can by the best in Paris there.
Btw, I prefer Paris-Brest
