I'm a slow eater by US or english world standards... but too quick for french people

Truth is, with work, I tend to be way too careless and quick, although I have my addresses and try to find the optimum in price/quality and time.
And many times a year, I like taking my sweet time, with 2 3 or 4 hours lunches

I have had an incredible experience in France in a top quality restaurant in Annecy (French Alps) and another one in Venice, that come to mind in the very slow yet wonderful category.
