Yen Ching Midlothian turnpike location only is still the best general Tso I’ve had in the area.

Edit: To add for me what makes it the best is fresh chicken + they get the crispiest of crispy perfectly while not over cooking the chicken and remaining juicy. This is what I see almost everywhere, overcooked dried chicken. There is an actual crunch to it. Also the sauce is thick and plentiful to be added to the rice. I also see a lack of sauce in almost every other place I’ve tried.
