Just to clarify, Remy makes the rounds of Les Chefs de France. Most of his times are during lunch, but the last round (5:20 pm) is during dinner.
Be aware that he makes a circuit of the tables once per time, so if you aren't at your table, seated, etc when he comes by, he doesn't come back and people are not encouraged to get up and approach him (unless you're at a table he cannot physically get to for some reason).
