Some of the things you could eat in other restaurants around the Vieux Port are on these signs. Oysters are "farmed" all along France's Atlantic coast, from Cap Breton in the far southwest all the way up to the Cotentin peninsula in Normandy. Muscadet wine, a dry white which many people think is the best "oyster wine" in France, is made just north of La Rochelle in the Vendée and up to Nantes on the Loire river. The oysters advertised here come from the Île de Ré, which is just a short drive over a bridge from La Rochelle.
Here's a blackboard menu from another restaurant, showing the day's specials. Customers have a choice of three formules — three courses for 26 euros, two for 21 euros (main course with either starter or dessert), or just a main course for 16 euros. There's a lot of seafood on the menu, including squid (fricassée d'encornets), tuna (tartare de thon), sea bass (filet de bar), cod (pavée de cabillaud), and haddock.
It was a Monday, which in France is usually a very quiet day, but in La Rochelle there were a lot of people out and about. It was because of the great sunny weather, I'm sure. By the end of October, people expect the weather to turn chilly and gray very soon. They take advantage of the last sunny days of the year by taking walks through town and sitting down for some food in a sidewalk café.
