I've been eating at River Tai for over a decade now and have never been disappointed. The prices cannot be beat (they have a whole list of meal-sized dishes for $3.99 all day every day!) and it all tastes delicious. They owners are a very kind elderly couple who have always been happy to accommodate my requests. Although the decor is not "modern" (and has not changed over the decade I've been eating there--why should it?), the restaurant is clean. The clientele is a wide mix, but appears to mostly be long-time regulars (always a good sign) and students. Great hot and sour soup.
