Wow... now I know why this place is open so late. Sure, Vegas is a city that's open 24/7. But while other places close up shop, this one keeps serving. I didn't even know Vegas had a Chinatown, let alone an Asian mall. I believe I even spotted a Ranch 99! Just like home.... heheh.
I tried the pho, which was decent, but my fiancee ordered the fish hot pot, cooked authentic Vietnamese style. What a taste bonanza! We got the sauce to go, as it could be cooked with a lot of other food.
Only qualms are, like others have mentioned, that the service can be spotty. I had to remind them to bring me my Thai Iced Tea after waiting 10-15 minutes for it. I suspect the waiters are just inexperienced, as many appear to be quite young.
