And the economic structure is highly centralised around Paris. In contrast to federal Germany, licences or concessions are often available from ministries in Paris even if the business is situated far from the capital city. Food and wine still play a big role in French business life. Entertaining is regarded as an important part of getting to know your partner. The French tend to take longer over their meals than British, Germans or American, for example.
Wine is seen as the ideal companion to good food, at both lunch and dinner.
By all means, enjoy the food and drink. However, avoid too much wine and rich food, especially during lunch. Your negotiating partner is probably inured to them. As the negotiations stretch into the afternoon, you may find yourself nodding off.
