This is a great place to eat in the Loop. (The Loop is also a place to look into when you come to St. Louis. There are lots of cool shops and bars, and it’s a popular hang out spot for college kids). TCC has excellent Thai cuisine, and they doubled the size of their restaurant about a year or two ago. This actually means that the service can be a bit slow (they don't seem to have added more workers when enlarging the restaurant), but at least you don't have to wait too long to sit down. The food is cheap and yummy, and you nearly always have enough to take home and eat for another day or two. I recommend their spring rolls and dish number 40. Most dishes can come with your choice of meat or tofu, so they are very vegetarian-friendly. The Thai iced tea is also delicious. Mmm, I'm getting hungry writing about it. I'd better stop.
