Each Friday and Saturday, Great Lakes hosts free tours of its historic complex. The Great Lakes grounds represent a remarkable convergence of Cleveland's past: They once housed the stables and kegging equipment for the Schlather Brewing Company -- a giant, back when our city was a beer-making hub. The brewpub also rests in the space once occupied by the Market Tavern (est. 1865), which later became a haven for tradesmen and city employees; legendary Cleveland Safety Director Eliot Ness frequented the place, and legend has it that the bulletholes marking the wall of the main bar were fired from his gun. Upstairs, the "Rockefeller Room" once served as the law offices for young John D. himself. There's a lot of history in those hops.
