Food is a hot topic of debate but travel website VirtualTourist has compiled its selection of 10 of the world's most iconic dishes and the best places to find them.
1. Pastrami Sandwich - New York City
Neighbourhoods grow and change but some things stay the same. A fixture in New York's Lower East Side since 1888, Katz's Delicatessen is a holdover from a time that has long disappeared from the old neighbourhood.
Less than a block from the Tenement Museum, which celebrates the immigrants who lived in the area in the early 20th century, Katz's is most famous for its pastrami.
The deli's superiority is so renowned that it has online ordering, shipping all over the United States and to any military address, a tradition established during World War Two.

The restaurant serves original Pad Thai, as well as a "superb" version with Thai noodles served in an omelette.

Traditionally, it was served Marinara or Margherita, with the primary difference being that Margherita features mozzarella cheese and basil on top. It was named after Queen Margherita of Savoy, who was served this style by a young chef when visiting Naples in the late 19th century.
There is no shortage of pizzerias in Naples but two of the most famous are L'Antica Pizzeria da Michele and Pizzeria Di Matteo, the latter near the Duomo and known for being the place where U.S. President Bill Clinton dined during the Group of Seven conference in 1994.
4. Frites – Brussels
Belgium is known for many food specialities, including waffles, mussels and chocolate, but one of its greatest areas of expertise is in frites, or fried potatoes called French fries by some.
Belgian frites are distinct for two reasons
