We use to go to Petite Auberge our first night and then at least once during our trip.
That was when it was owned by a French couple, who were a favorite of ours, along with their dog MicMack.
We heard that it is still a good choice, but have not spent too much time eating in Marigot.
Hopefully we will try them soon---we did go to Be Cool, another great choice at the Marina.
