If you're in the Cincinnati area, be sure to check out the recently-opened Old Kentucky Bourbon Bar. It's on Mainstrasse in Covington, KY (right across the river from downtown Cincy) It features 127 (and counting) American whiskies --- mostly bourbons. It's owned by Molly Wellman, who also owns Japps on Main Street in Cincinnati (which is absolutely the best place in the area for classic cocktails)

You can get a beer there (I think) but its really about the whiskey!
