The dish you get at these ramen bars is not something you sould easily make at home simply because of the economies of scale -- too much prep for the small quantities required. Though called Ramen, the noodles are the least important part of the dish. At Sapporo, for example, you have the choice of several flavors of soup (miso, shio, shio bata, sesame, curry and others) and in addition to noodles, you get two kinds of pork (sliced and ground), two kinds of fish cake, corn, bean sprouts, scalions, spinach, seaweed and more. I suppose you could go to a salad bar and pick up the ingredients so you didn't have to wash and slice them yourself, but why bother when you can get the real deal prepared by an experienced cook for under $10.
