At Le Baron Rouge on Rue Théophile Roussel,
people were lined up to eat oysters on the street. 
Monsieur was shucking quickly for the waiting crowd. 

It was as close to a "feeding frenzy" as you will find in Paris.

(Merci, for the correction, mes amies -
I was "eating on the flea" and I meant "eating on the thumb")
