In this bakery you can have authentic French bread in the shape of a turtle or a crab, for instance.
There are two other things that drew my attention when I was there: the first one is its glass cabin which you could look through and the second one is the microphone for asking questions to the bakers inside.
They best selling product is the “Clam Chowder” or crab soup. This soup is served in a bowl made of bread with a top on it. The funny thing is that you can eat the bowl itself , which will remain crunchy, when you are finished with the soup. Nonetheless, I don’t think you are gonna have enough space for it in your belly…
