Charm Coffee is a coffee shop on a quiet residential alley in Lang Ha, Hanoi. It serves latte, matcha latte, cold brew and fruit tea, with drinks that are not overly sweet and made one cup at a time. There are indoor and outdoor seats, a space with books and a piano, and office workers crowd in at lunch so weekday evenings are quieter. The tables are low, which makes your back uncomfortable after sitting for a long time.
