None of the above choices .Because it was open late at night .Because it had good coffee .Because the narrator 's buddy worked there .
Why did they go to the diner ?
My buddy and myself were living in Eau Claire at the time and would go up now and again for a visit do a stay the weekend kind of thing . Anyways we went out one night playing pool stayed out late till like three AM hit the local 24 hour coffee shop / diner typical sat night . So we finally drive home it was about 4:30 AM just before sunrise .
