The table on which former US president Barack Obama shared a meal of noodles and beer with chef Anthony Bourdain in Vietnam two years ago is now encased in glass.

According to a photo posted by the American chef and television personality on Instagram, the table is now on display at the Hanoi street food restaurant.

The famous meal, which Mr Obama had while on an official trip to Vietnam, reportedly cost US$6 (S$7.90).

The idea of putting the table on display had come from customers, said owners of Bun Cha Huong Lien restaurant, reported the BBC.

"The customers love it, many take photos next to the table," said restaurant co-owner Nguyen Thi Hang Nga.

Bowls, plates and the beer bottles used during the meal are also on display, but only after they have been washed, added the co-owner.

In his Instagram caption, Mr Bourdain said he is "not sure how I feel about this".

According to the BBC, the practice is usually reserved for the country's top leaders, such as Ho Chi Minh.

The BBC added that it is believed to be the first time a foreign dignitary has been remembered in such a way.
