Halloween-themed drinks and a good craft beer selection. Jekyll is can be a nice change of pace from the regular shenanigans of Souf Side. Definitely a lot calmer than the Carson Street action. It's a good mix of hipsters, bros, and whoever else wanders in. It's not my favorite bar, but it's doable since my friends like it.
P.S. The scariest part of the bar is bathroom. Hands down.
