Continetal doesn't, in this case, mean 'the continent of North America'. It actually refers to the style of cooking popularized by the 'fine cuisine' restaurants of France an Italy.
'Cuisine' means something a little different than 'food'. Food is just what you eat. 'Cuisine' is what a People or group eats. For instance Hungarian cuisine contains a lot of paprika and potatoes- even though the people of Hungaria have changed their diet a lot in the last 30 years these items are integral to both Traditional and Modern Hungarian cuisine.
So 'continental' refers to style, and 'cuisine' the substance. The 'American' part is probably the most open for interperetation. Since traditional American cuisine is fairly limited, and modern American cuisine is such a broad term, it probably means something in-between.
Examples of things you're likely to find on the menu:
Classic Hamburger with grilled portabello mushrooms and a garlic aoli sauce for lunch. Beef Wellington with pate of venisson and blueberries for dinner.
In short, all the plates will be white and clean, the water glass will have a stem, and you'll probably want to wear a jacket. I would guess that in most places you could reasonably expect to pay $25-40 per entree, although this could vary wildly in some restaurants. Bon Appetit!
