This is as authentic as you're going to get.
I'll be straight up when I say that places like this can make me nervous. The mall itself is sketchy...and it's in a sketchy part of town. I make it this way every few weeks for some bánh mì at Le's, but came on a day that Le's was closed. Dim sum?...or the place with ducks hanging in the window? We opted for the ducks in the window and chose Hong Kong BBQ.
When you enter Hong Kong BBQ...you can tell there's going to be a communication issue. There is literally...not a single thing resembling "American" in this restaurant. I knew I was going to like this place. I did my best not to look back at the kitchen. We all know what that is going to look like...and I'd rather play dumb. Dangit! I looked.
The service was quick and the food was great! We were even entertained with Chinese soccer on their small TV.
I'd recommend coming here if you're an adventurous person...otherwise...you'll never make it as far as the door...much less the table.
