We've covered Tin Roof a fair amount here, which of course makes sense. And to their credit, after a slow start they've made some nice efforts to not only diversify, but really improve what they already have. The tap room over at their brewery on Nicholson can be a lot of fun, with some specialty offerings available that they don't release and experiments. They have some TVs, games and host a trivia outing (usually with food via City Pork) on Thursdays. It can be a lot of fun.
Anyways, they recently released a new spring seasonal, their Yonder Hefe, which is available in kegs or six-packs around town.
