This might turn out to be a long review, but please bear with me:
My sister and I ate at this restaurant two nights ago and we had a pretty awful experience. She had eaten here a couple times with no issue before, but she had always gotten the same dish. That night I did not feel like eating the dish that she suggested (the portions here are pretty generous, so this dish easily fed two) so we opted for other dishes. I had ordered Curry Chicken Rice and she had the Seafood Noodles.
Admittedly, my food was pretty tasty, but my sister said her noodles had way too much sauce in it and that it was incredibly salty. We called our waiter over and she kindly asked for it to be taken back. Their manager comes out of the kitchen with the dish and tries to get my sister to take it back. She said and I quote, "We in the kitchen all tried it and it's not too salty. The dark colour is from the oyster sauce that we use to flavour the noodles and it is perfectly seasoned." My sister protests that she did indeed try it and was that it was just deemed too salty from the colour. The manager looked pretty angry/frustrated and just walked away.
Instead of remaking the dish, she orders Roasted Quail w/ Rice, and they take at least 40 mins to bring out her new dish (the place was not busy) and her rice had been pretty dry and stale/old tasting. The night had already been soured, so she decided not to say anything. While we were eating, we could hear the workers in the back gossiping in the back about us (we sat right beside the kitchen), granted this part was anecdotal, but was extremely unprofessional and was just another sour note on our already dampened experience.
After we finish up, we got up to pay and we find out that they had charged us for the dish that she had sent back. Instead of protesting or making a scene (there were other people behind us waiting to pay), we decided to just quickly pay and leave.
My sister ordered a dish and it was too salty, she kindly asked for it to be taken back, the manager came out and argued with her to try to get her to finish it. After ordering a different dish, they take 40 minutes to bring it out to her and her new dish was less than sublime. When we went to pay they charged her for the dish that she took one bite of.
Please don't eat here, there are plenty of (especially in YYC) fantastic places to get Vietnamese cuisine.
Definitely do not recommend.
