Hi. I have taken a number of RS tours, though not this one. I must say that I have at times found there is TOO MUCH food for me at the group dinners. I am not sure, but the input of the individual guides may be a work regarding the menus. There seems to be most always a choice, but I noticed when at Mont. St. Michel, we were eating the tourist menu. Disappointing. But then, that is the whole character of Mont St Michel at this period, right - tourist-centric.
When it comes to non-tourist-centric places, which I think many of the RS restaurants are, I sometimes feel guilty for not being able to consume everything they put in front of me. They are trying to showcase their cuisine and cooking, and sometimes I end up eating more than I would just to be compliant and not offensive to our hosts. Hooray if Le Doggie Bag becomes popular. Anyway, I am steeling myself in future to not feel badly if I cannot scarf down all the food given me.
I like the camaraderie of the group meals, but the good news is, group members frequently meet up for non-tour meals, and then the opportunity to select is as wide open as the menu.
I don't know that I would characterize the food as heavy necessarily, but it has sometimes been too plentiful for me. I think if you have specific concerns, a conversation with your guide would be helpful.
PS, I have had some fantastic meals with the RS groups, too. Amsterdam comes to mind. I thought I was eating sushi grade tuna, but it turns out to have been beef. Wow. I hope to return to repeat that experience.
