Pretty good for a food court.
For being tucked away in a mall food court, Oma's offers very good Korean options. I would only avoid the lunch specials, which sit out in trays for a long time. The soups in general are excellent, I'm particularly partial to the soodubu jigae.
I saw the previous comment, and strongly disagree with it. Oma's Kitchen provides great "real" Korean food. If you visit there at normal school hours where a lot of UT students passing by, you'll notice there are a lot of Asians (especially Koreans) (Myself, is an Asian too) eating Oma's Kitchen's great food! Please be fair... Repect "DIFFERENT" food.
