It’s affordable and it’s convenient. But the real kicker is – even a former U.S. president has given it his stamp of approval. Well, take a trip to the Centennial State to experience exactly that. Boulder, Colorado is home to The Sink, a joint that has had the honor of being visited by none other than Barack Obama.
