Bluegrass Brewing Company is a staple of Louisville. They helped to pioneer the microbrewery scene, and since 2010 they have occupied a former bank space downtown.
When in Louisville you have to try a hot brown. The hot brown at BBC features sliced turkey, tomatoes, bacon, mornay sauce, cheddar jack cheese, and smoked paprika served open-faced over sourdough toast ($17.90). This is a great example of this famous Louisville dish and the serving size is large enough that it could be shared.
Bluegrass Brewing Company is worth a stop for great pub food and while you are there try a dank IPA.
