The leaders met for an intimate "social dinner" after a handshake and some brief remarks at the historic Metropole Hotel in the communist capital, their second face-to-face following the historic summit in Singapore last June.

The evening offered more than just press ops as the leaders sat down to break bread with a few close advisors at the five-star hotel.

The menu, details of which were released by the White House, appeared to attempt to bridge culinary cultural gaps with Korean and American classics on offer.

First up: Shrimp cocktail with avocado, lettuce and thousand island dressing, a nod to the popular US salad topper.

Next came grilled sirloin with a kimchi-stuffed pear in honour of the Korean dinner table staple.

A runny chocolate cake topped the feast for Kim and the US leader, who is known to have a healthy appetite.

Alcohol was off the menu -- Trump is a noted teetotaler. Instead a virgin cocktail of persimmon and honey was poured for the leaders, who were pictured at a round table, covered with a tablecloth and set with six wine glasses that looked to be filled with water.

"Great meeting and dinner with Kim Jong Un," Trump tweeted after the meal.

Among those at the table were US Secretary of State Mike Pompeo and Kim's top envoy, Kim Yong Chol.

Wednesday night's grub was not Trump's first spread of the day. He earlier lunched with Vietnamese Prime Minister Nguyen Xuan Phuc -- a five-course meal covering the varied delights of Vietnam's cuisine.

Mango salad, fried spring rolls, king crab and Hanoi's signature 'cha ca' fried fish were among the dishes served, followed by a dessert featuring lotus seeds, longans, and white wood-ear mushrooms served warm and in a light sugary syrup, the White House said.

Kim and Trump are set to meet again Thursday for their second and final day of talks about North Korea's nuclear arsenal.
