This is a traditional, large Vietnamese Buddhist restaurant. You will see people inviting the monks etc there. As such, it is a good Vietnamese experience, but not the small "Quan" for everyday.
The food is good, but typical also. This means a wide range. My VN friend liked the food and she is very choosy, so it gets an authentic tick. It does stand up well to other places. The prices are standard.
We had a hotpot (Lau) one time, and rice another time.
For some reviewers complaining about the lack of flavour, the problem is a lot of VN vego dishes are not strong. But something braised with pepper (kho tieu) or Tofu with lemongrass and chili (Dau hu xa ot) are stronger, and it is traditional to add chili or sauce at the table.
Lastly, comments about free tea made us laugh - that is standard for the vast majority of local restaurants and cafes in Vietnam.
It is 4.5/5 as a real VN place that I enjoyed. Have to round it up to 5 for HC!Pros: Good food, Authentic, Pleasant
Cons: Not much
