Simple, strong viet coffee. You'll def be awake after drinking this! It's quite reasonably priced - like the same as Starbucks.
Service here is really good! The girl at the front was helpful and friendly. She advised that getting less sweet might be a bit too bitter so I opted for 50% instead. It was a good choice!
They also have a stamp card for each time you make a purchase.
Also, they sell viet coffee equipment and ingredients in case you want to DIY at home!
