YES! This place is LEGIT! Those of you claiming its not authentic....wah-wah. Very delicious food and priced very appropriately. The wifey and I have been in here a couple of times now and have sampled a large section of the menu.
The first time we were in our server referred to the restaurant as "a spring roll bar" and all of the spring rolls we have tried have been very good. That miso ginger sauce for dippin is freakin awesome.
The shaking beef might be the most expensive thing on the menu (at $15) but it also might be the most delicious thing I've ever eaten. And while the pho may not be the best in Phoenix, it is easily top 5. Happy Hour pricing is awesome: 2 people, with a cocktail or a beer, and full bellies for less than $30. The food is delicious and the people are very nice.
Definitely check this place out if you're in the area, I know I will continue to come back here.
