Porter Ale House since its opening in January. They are located on the ground-level of a new apartment building on South First Street, about a quarter mile north of Ben White/Hwy 290, and on site parking is available. The people who I know who have been to Porter have all reported very good things, and can now say, I concur with their findings!
Friends and I met for happy hour (Sunday - Thursday, 5 - 7 pm) on a recent Tuesday, and they offer drink specials and a few small plates at reduced prices. I started with a Tito's Mule in the requisite copper mug, that was refreshing, but not real strong.
