One of my favorite things about living in South End is being able to walk or ride to Good Bottle. It's easy to get there just off the rail trail/light rail. The owner, Chris, is a super friendly and knowledgeable guy. They have a great assortment of beers (bottles and cans) to choose from and they also have plenty of cool events (like Beer Camp or even some Saturday morning events). They do have a wall of cold beer offerings as well. Make sure to follow on Twitter or the social media of your choice to stay up to date on new releases and events. About once a week or so, they'll run a special like $4 NC beers or what not that is just enough to motivate me to go from having a beer on my couch on a Wednesday evening to heading down for one of the 12 beers on tap.
There are a lot of craft beer joints around Charlotte, but Good Bottle is definitely one to frequent.
