This place has been in business for many many years so they must be doing something right. It looks ghetto but that's part of the experience of a Vietnamese restaurant. It wouldn't be the same if it was all clean and modern. Granted it would be nice if they expanded. Known to be the best in Toronto this place is almost always packed in the evening so don't be surprised if you have to wait just to be seated in a row of tables with people sitting 1 or 2 chairs away from you.
Service is always nice even at peak hours and the wait time for food is very minimal.
Cheap meal and a bargain for the quality and authenticity you're getting. This is the closes thing to Vietnamese cuisine we have in Toronto. Definitely worth a try 100%.
