This place is up by the Liberty High School Intersection, I think that is Sawmill Pkwy and Home Rd. It is right before it on the right (if headed North). Pull in where you would enter to go to the Marathon station.
I have been to this place, its great. They have tons of different beers in the cooler and home brew supplies. The prices are okay, Gentiles is probably a little cheaper but if you are on the Northwest side this place is a lot closer and easier to get to.
They are also a state liquor store and wine shop. They have beer and wine tastings there on Fri/Sat for a fee. Overall a cool little shop.
This place is great for Beer, Liquor and Wine selection. They have a fair amount of brewing supplies and they will continue to grow I'm told. This store is owned and operated by the same proprietor that runs Blacklick Wine and Beverage on the east side. Both are very nice establishments IMHO.
