We are at U of I for Halloween and looking for a quick bite of Thai. We found Thara via Google maps and decided to give it a try. The staff was friendly and accomodating - we arrived in full costume garb and acted the parts (magician and bunny and three blind mice).
The place was crowded and service was slow, so probably not a place to go if you are in a hurry, though they could have been under-staffed. However, the food was excellent. The Tom Kha soup was among the best I have ever had, the pad sie ewe thai was delicious (according to friends) and the spring rolls were fresh.
A couple of call outs: they don't serve alchohol, it was a bit pricey, but we are used to Chicago, where there are thai places on every corner. Finally, when they spice things, they really heat them - if you want mild, really stress that.
