The Alliance Française in Hanoi is a fancy place.
It’s in an Art Deco building, and has within it classrooms, an expensive café, an art gallery area, and a TV that plays FRANCE5 MONDE or something similar at all times. Students attempt to do their homework beneath the screen.
The library is on the second floor, and is quite nice– except for the magazine and newspaper section. The newspapers are years old, and often the magazines are as well. If you are aching to read an issue of Le Monde from some random date two years ago, they may have a gently used copy available at this location. Similarly, while the magazines are neatly ordered, the subscriptions for many of them expired years ago. I’m not sure who is super-interested in old copies of Sciences & Vie and prefers a ragged copy to just looking online, but again, this is the place to come.
You will find many Vietnamese students studying French within the library, constantly looking up words and cramming. One young fellow wanted to practice his French with me. I did so, but he couldn’t understand anything I said in French. He was then disappointed to learn that I wasn’t French, and recoiled when I told him my age.
BONUS: Open Saturdays, and the famous rice ice cream shop is a couple blocks over.
