Al Michaels -- BACK IN THE DRIVER'S SEAT ... After DUI Arrest

Just days after his DUI arrest, Al Michaels ventured back out to Hollywood to another fancy restaurant ... but instead of hiring a driver, he decided to take the wheel himself.

TMZ was outside of Toscana restaurant in Brentwood last night when Michaels -- along with his wife -- rolled up in the same black Mercedes-Benz he was driving the night of his arrest.

We broke the story ... Michaels was popped for drunk driving in Santa Monica on Friday after making an illegal U-turn in front of cops. Sources tell us his blood alcohol level was JUUUST above the legal limit.
