Went to Old World Brewery for a tour on a living social voucher. My friend was a bit skeptical about the place at first as the outside looked like a post office (Found out in the tour it actually used to be a post office). Walked in with my friend and the place had a good group of people waiting for the tour. The owner promptly accepted our voucher and proceeded to fill our beer flights. The owner brought the beer flights which had been poured generously and gave us two bags of chips to munch on. The beer was excellent (I especially liked the Arizona Honey wheat and Dark knight porter). Went on the tour and the owner's dry sense of humor made it very entertaining. I had a great time and would definitely come back.
