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 .

Give answer the following question using evidence from the above passage: Why did they go to the diner ?
Because it was open late at night .
