I have traveled a lot, so I can offer opinions (I emphasize opinions) on different restaruants. American restaurants usually feature more steak and beef in general. The portions are bigger, but contain much more fat. (I can say this because I'm an American). Americans also eat much more meat of every kind. French restaurants have smaller portions, with much less meat, but the taste is more intense. Italian restaurants (at least in the U.S.) use a lot of noodles in one form or another. Bread is also emphasized. German restaurants serve a lot of pork and potatoes in many different dishes. They are not spicy. There are no English restaurants because English food is just not that good. It seems to combine many of the the disadvantages of the food of the other nations together. If it wasn't for Indian, Pakistani and Chinese immigrants, English restaurants wouldn't have much to offer. I lived there for a year and liked England very much - just not the food.

the difference is comparable as the difference you can make between a corean restaurant, a chinese restaurant a japanaese restaurant, or a vietnamese reataurant, etc. that simple.

Italian= pizza, pasta, veal dishes eg parmigiana, chicken cacciatore, panna cotta, tiramisu. French= snails, frogs' legs, créme caramel, french fries, coq au vin, mousse, profiteroles. American= see above also hot dogs, burgers, fries, icecream sundaes English= meat pies, pasties, sausage rolls,sausages and mashed potato& peas, battered fish and chips,plum /bread and butter puddings, sponge cake, trifle, sticky date pudding. However wherever you travel, including Australia, most countries now have an international cuisine and feature all the above food and more, even in Asian tourist destinations e.g. VietNam, Indonesia, Thailand.

Italian - heavy tomato flavor, creamy sauces with lots of pasta and noodles, very simple dishes, olives, use of fresh vegetables and herbs French - lots of different sauces, quite expensive, strong flavors, smaller portions, very visual, sweet and wonderful desserts, focus on wine American - often fried,baked or grilled, very fatty and oily, very salty or very sweet, don't really use sauces, emphasis on different meats Chinese - very rich and savory, uses all kinds of vegetables and meats (especially different and all parts of the animal), great variety, highly addictive, best food in the world :)
