Honestly don't know why I haven't review this place earlier. I'm Shanghainese!
So, in my honest, shanghainese opinion, this is the best place to get sheng jian bao in Las Vegas. Most places don't fry the bao long enough or quite right so the dough is still raw. This place fries the outside perfectly and you can see the burnt yumminess on the bottom of the bao. The top is glistening with a few sesame seeds. These baos won't explode in your face once you bite into them, but they will ooze out delicious soup. The texture and the taste of the pork is done quite well and the ratio of meat to doughy skin is good too.
Other stuff I recommend are the shanghainese small won tons, drink chicken, lamb chops, and pork thigh.
The place is a little pricey but honestly, this place is authentic or as close to authentic as you can get to Shanghainese food in Vegas. Service was very attentive for us (maybe because we're shanghainese?) lol. Oh, and park is a hassle. Gotta get lucky with that!
