If you’re going to compare them to the old yangs just leave. For not even being open a week they did a great job! Line out the door and the phone never stopped ringing. A few small things my lo mein noodle were still firm, fried rice could have used more soy sauce. I did takeout and by the time I got home food was room temperature. (but that could have been my 20 minute drive home) 
But again for only being open a few days I was very happy and will be back again.
Keep it up, you’re doing a great job!
