For my beautiful girlfriend's birthday, we traveled across the state of Michigan in order to go to Slows Bar-B-Q in Detroit, a restaurant she'd seen on the Food Network. Having lived in Texas for two years, I was the self-proclaimed judge of whether or not this was real Barbecue.
My verdict, in case you couldn't tell, is that you can definitely get authentic barbecue at Slows in Detroit. All y'all Northerners should consider heading over there, because it's certainly cheaper than driving all the way to Texas. (However, if you choose to drive to Texas for it, drop me a line: I might need a ride back to school in August.)
