I usually don't like 'best' lists but a previous topic about French cuisine got me thinking about its popularity and I still believe it is #1 over other cuisines when people want to dine out for celebrations, romance, vacations and the like.
Here's a link I found today that lists the 50 top restaurants:
Note that it states: "More countries than ever appeared on the list, but it was the French who conquered the globe with 10 restaurants on the list. (It should be noted that an astounding 24 entries out of the top 50 restaurants chosen serve French food.)"
I'm not stating that I don't enjoy Chinese, Japanese, Italian and other cuisines as well but I just believe French cooking techniques, their recipes, including desserts and wines are really supreme and have added to most 'fusion', Mediterrean/California style cuisine as we enjoy it today.
