(Visited 09/2012): Giant Eagle is located in Upper Arlington between Northwest and Tremont in a shopping plaza. There is a large parking lot shared by the stores.
The beer section is on the right side and is kept in coolers and on shelves.
As with more and more grocery stores these days, Giant Eagle has a fairly extensive collection of beers. Domestic craft brewers are well-represented, including many Ohio breweries like Great Lakes, CBC, Thirsty Dog, Rivertown and others. Many imports from Germany, the UK and Belgium as well. Some singles available.
Service is pretty typical for a grocery store.
All in all you probably won’t find much in the way of one-offs or extremely limited edition brews at a store like this but they carry just about all the common craft breweries one would want.
