Best I've found in Calgary. Great menu, great food, great grotty soup kitchen ambience. Everything I've tried was wonderful, and although not cheap, was priced reasonably. Check out the quail appetizer, and the curried seafood soup.
If you've seen my other reviews of Vietnamese in Calgary, you'll know I'm rather picky, so I'll let loose with my complaints about this joint: first off, it's all the way across town; secondly, they don't stay open late enough to conveniently go there regularly.
If you're local, you're damn lucky.
