"West Lake Bún Chả
We beg to announce:
Restaurant begs to increase prices
5,000 đồng [21 cents] per portion
[...]
We beg to thank our valued customers!"

I've started to notice price increases, but they're still extremely rare here. I'm still paying 85 cents for bánh mì, $1.28 for bún thịt nướng and $2.14 for phở, etc.

The world heard about bún chả when Obama and Anthony Bourdain had it Hanoi in 2016. West Lake is in Hanoi.
