There is no doubt that in every country you go,you will see that some type of food is most popular and everybody tends to eat these kinds of food.Maybe it is common among the people of that country because they think it fills their taste,although all type of food has an essential materials in it that can help to have a healthy diet.
Blah Blah Pizza with Sanjab Sauce.
There is no 'best' food, same as there is no 'best' car.
In my humble opinion, the best of the best is the hot, steamy, freshly fried potato with lots of sweet onion atop of it and a little bit of salt, accentuating the sweetness better. It doesn't taste like french fries at all. The taste is rich and brings forth images of home and family, partaking in a meal together.
It's hard to say that one type of food is the best, but as Italy is known for pizza and spaghetti, France for cheese, Romania is known for polenta and cabbage (sarmale). Is a pity to visit a country and not taste the traditional food.
