There are numerous North and South Indian restaurants all around Singapore, most of them located in Little India. Singapore is also well-known for its fusion take on Indian cuisines. The fish head curry for example, is a local creation with a strong Indian influence reflected by its complex use of spices. Indian influence on Malay cuisine dates to the 19th century. Other cuisines which borrow Indian cooking styles include Filipino, Vietnamese, Indonesian, and Thai. The spread of vegetarianism in other parts of Asia is often credited to ancient Indian Hindu and Buddhist practices.
Indian cuisine is also fairly popular in the Arab world because of its similarity to and influence on Arab cuisine.
The popularity of curry across Asia has led to the dish being labeled the "pan-Asian" dish. Curry's international appeal has been compared to that of pizza. Though the tandoor did not originate in India, Indian tandoori dishes, such as chicken tikka, enjoy widespread popularity. Historically, Indian spices and herbs were among the most sought-after trade commodities. The spice trade between India and Europe led to the rise and dominance of Arab traders, to such an extent that European explorers such as Vasco da Gama and Christopher Columbus set out to find new trade routes with India, leading to the Age of Discovery.
