After moving from California to France, we found ourselves missing a place to go for a good…read moresandwich, and for a good coffee with pastry/cookie. Gontran Cherrier fulfills that void brilliantly.
The sandwiches are very affordable and tasty, the cakes and "patisseries" are great. My favorite sandwich is the "black sandwich". For dessert, I highly recommend the lemon cheesecake, for instance. And then, coffee is excellent too, with again a large choice of danish or pastries to eat with.
The employees are very nice. And unlike many bakeries in France, there is plenty of room to sit.
After you visit the château of Saint-Germain-en-Laye and wander in the nice shopping streets, this is the best you want to stop for lunch or coffee.
