I always find myself gravitating towards Ginger Root when I'm at Union South, not because I find the name particularly attractive or their menu particularly appealing, but because it is (sadly) one of the healthier options there. The portions are also extremely generous for the price. A $5/small bowl (your choice of rice + one entree) can usually tide me over until dinner.
Other than that, there is not much to say about Ginger Root. If you are a fan of Panda Express, you might find some comfort in the look and taste of the food here. If you are looking for 'authentic' Chinese food, you'll be hard pressed to find something here that will meet your standards.
