First of all, the menu is not required to state that service IS included. In absence of any other statement on the menu, the assumption is that service IS included.
Sadly, some restaurateurs and servers are less than honest with Americans, who are accustomed to tipping 20%. In France, and on the French side of St. Martin, unless the MENU states that the service is NOT included, then you can assume that it is.
Jon and Bev, the answer to your question is yes, but it must be noted on the menu, not the check. You need to know before you order if you're going to be expected to pay an additional amount for service, as the norm is for it to be included in France. If it's not printed on the menu, but is on the bill, then you're being taken advantage of as an American who doesn't know better.
