Tarka Indian Kitchen, located in the same shopping center as Ikea (off i-35 and 1431 in Round Rock) is a fast-service Indian restaurant. Considering that it's just a restaurant where you order at the counter, I found the prices to be too high. Regardless of price, the food was merely average. I chose a medium-level for spice, which still had hardly any flavor. Others in my group who chose mild spice said their food was just OK. The naan (which was available for an extra charge) wasn't that fresh or hot. The rice was nice. (Yes, saying the rice is nice is very faint praise!)
The staff was friendly enough. The dining room was pleasant enough. And, they even had high-chairs. But, those positives weren't enough to overcome the rather bland food.
I'm not an expert on Indian food, but I've had plenty of better meals at other restaurants.
