For our first night in Paris in September, we are planning on having dinner at either Les Cocottes or Café Constant or Le Violon d'Ingres in the 7th. I think only Le Violon d'Ingres accepts reservations and I usually regard that as a plus. But we are planning an early dinner that night and plan to arrive at opening time for dinner - so I don't think a reservation or not is as critical in this decision.
Which of these three restaurants would you recommend if you have to pick only one of the three for dinner? Could anyone give me a "compare and contrast" about their differences and which is thought to be the best, which is more formal / casual and so forth?
Your assistance is much appreciated! Merci!
