Hanoi has rich culinary traditions. Many of Vietnam's most famous dishes, such as phở, bún chả, chả cá Lã Vọng, bánh cuốn and cốm are believed to have originated in Hanoi. Perhaps most widely known is Phở—a simple rice noodle soup often eaten as breakfast at home or at street-side cafes, but also served in restaurants as a meal. Two varieties dominate the Hanoi scene: Phở Bò, containing beef and Phở Gà, containing chicken. Bún chả, a dish consisting of charcoal roasted pork served in a sweet/salty soup with rice noodle vermicelli and lettuce, is by far the most popular food item among locals. President Barack Obama famously tried this dish at a Le Van Huu eatery with Anthony Bourdain in 2016, prompting the opening of a Bún chả restaurant bearing his name in the Old Quarter.
