<p>If you want relatively cheap, yet excellent, Chinese food, then go to Yenching. I can't remember which street it is but you could probably look it up online. I think if you look at a map of harvard yard, it is immediately south of the main yard if you exit out of one of those south gates and you keep walking to the left (even though it would be east on the map). It is really worth the search. Excellent, excellent food.</p>
