This was my favorite Chinese restaurant within walkable distance from CMU, as it is down the street on Craig Street. The interior is kinda strange because it's adjacent to a store (you can see through the windows) and the kitchen is like in a weird corner. The seats aren't particularly comfortable either, but that's okay. The wait staff is pretty nice.
Go here for their $5.60 lunch specials that include favorites like chicken and broccoli, black pepper steak (my favorite one). The portions are a bit small, but not bad. They do have a tendency to drown food in sauce, though.
