Arabia:

At Arabia if you don't retch after a meal, means that you didn't like it.

India:

At India you don't need to taste all the foods but you need to clean your plate. Also you can't left the table if the older person hasn't finished.

Marios

  
• In France it’s considered rude to cut the lettuce in salad!!
  
• In Mexico it’s actually ok to be late. Always being late for at least 30 mins won't annoy anyone, since the hostess has more time to prepare the dinner!!
• In Bulgaria you shouldn't bring yellow flowers to the hostess. They symbolize it hatred!!
• In England, bananas should be eaten with a knife and fork, a custom that dates back to the 19th century when this fruit was viewed as an exotic treat.
• In Austria you have to make eye contract with the person you clinc glasses with!!
• In Tanzania, drinking beer from the bottle is very rude-it should be poured into a glass!!
• In Italy, when it comes to pasta only, you don’t have to wait for everyone else to start eating; however, you must wait for everyone to be served before digging in on all other dishes!!
• In Portugal, bringing wine to the hostess is considered an insult!!
• In Russia and China, if you leave some food in your plate, it means that it was enough to enjoy it and not being too much. But, if you do the same in India or Philippines it shows to the others that you're rude and wasteful!!
• In Japan, when eating ramen, you’re expected to slurp enthusiastically. Be careful though, as it’s easy for the ramen to end up all over yourself if you overdo it!!

1. Hamburgers, U.S.

   Although the origins of the hamburger are disputed, there is no argument over the popularity of this classic dish. Toppings and accompaniments vary from region to region, but for an original version visit Louis’ Lunch in New Haven,Connecticut, which has been serving hamburgers since 1900 and claims to be the oldest hamburger restaurant in the U.S. 
   Planning: Louis’ Lunch is open most days for lunch and some days until the early hours of the morning.

2. Ackee and Saltfish, Jamaica

   Despite ackee’s unhappy origins as slave food, Jamaicans have reclaimed it as part of their national dish. A nutritious fruit with a buttery-nutty flavor, ackee resembles scrambled egg when boiled. Jamaicans sauté the boiled ackee with saltfish (salt-cured cod), onions, and tomatoes. Sometimes the dish is served atop bammy (deep-fried cassava cakes) with fried plantains. 
   Planning: Jake’s, Treasure Beach, is renowned for ackee and saltfish and also offers cooking classes.

3. Coo-Coo and Flying Fish, Barbados

   A polenta-like cornmeal and okra porridge, coo-coo pairs perfectly with flying fish, which is either steamed with lime juice, spices, and vegetables or fried and served with a spicy sauce. 
   Planning: The Flying Fish restaurant overlooking St. Lawrence Bay claims to be the Barbadian national dish’s home.

4. Bulgogi, Korea

   Beef bulgogi (fire meat) is a dish of thinly sliced, prime cuts of meat marinated in a mixture of soy sauce, sesame oil, garlic, onions, ginger, sugar, and wine and then grilled. It is often eaten wrapped in lettuce or spinach leaves and accompanied by kimchi (fermented vegetable pickle). Many Korean restaurants have miniature barbecues embedded in tables where diners grill the meat themselves. 
   Planning: Seoul’s upmarket Byeokje Galbi chain is a bulgogi sensation.

5. Kibbeh, Lebanon/Syria

   Dining well Levantine-style often means sticking to the delicious mezes(appetizers). Kibbeh, a versatile confection of ground lamb, bulgur, and seasonings, is a core component of mezes. It is often fried in torpedo or patty shapes, baked, boiled, or stuffed, but is tastiest raw.
