This is the 2nd Ay-Chung I've been to in the US, and of course nothing can compare to the original in Taipei. There's also an Ay-Chung in LA, located in Focus Plaza in San Gabriel. I never liked it that much since once you've had Ay-Chung in Taiwan and you can't really compare them. San Gabriel location's quality just isn't there so I was crossing my fingers when I came here.
We got a bowl of Ay-Chung noodles: It was surprisingly good! Way much better than the location in San Gabriel. The broth/soup base is much more flavorful.
Also got the popcorn chicken :] When a place fries the chicken with basil, you know it can't be bad. We also got the oyster pankcake as a side. It's not bad but they do use a lot of cornstarch. A lot of places use a lot of cornstarch as a filler. The pink/red sauce isn't bad though.
Also got the Stinky tofu. Wow they actually have the big pieces here. Most place in the states serve these small bite size stinky tofu and they're just not as good. I was surprised when they had the bigger ones. It's just much more enjoyable than eating the tiny cubes of stinky tofu.
Of course you can't eat Taiwanese food without getting a milktea or some sort of drink. The drinks here aren't bad at all. I would come here any day rather than paying 4-6 bucks for a large down the street at Tea Station.
They got a lot of the typical Taiwanese fare you expect. For the limited selections of Taiwanese food around the area, Ay Chung is not a bad option if you are craving some Taiwanese food in Vegas!
