Picked up my FIL from CLE earlier today.
He said there was Bug Light, Miller Light, and MGD for free.
Great Lakes Dortmunder Gold and Heineken were $3.
Better off in the CLE Airspace Lounge where they give a $10 food and beverage card for you and for each of your guests (even when entering for free via AMEX Plat).
Got a fantastic bottle of Great Lakes Lake Erie Monster seasonal beer last time with my card.
