We arrived at Noi Bai airport at around 4.30 pm, pretty early as our departure time was on 6.45 pm. This enabled me to walk around the small Noi Bai airport.
Inside the Noi Bai airport departure / arrival waiting area, it was pretty empty without much passengers. And, amazingly, the chairs are all hard steel seat. Inside this area, which was after checked-in and immigration checked, there didn’t seem to have any restaurant available. However, there are 2 restaurant at the highest floor of the public area in the airport, albeit the price is expensive.
