The beer is excellent, of course, although admittedly I tend towards more experimental brews such as can be found at other local breweries in the area (won't name names out of respect, but hence the 1 star docked). But GLBC is the ambassador of the midWest, especially CLE, in many respects, and the title is well deserved.
If you do make it down to the gastropub, don't skip out on the food. The fare and recipes are simple but never cease to delight. I highly recommend the Mac n Cheese, the poutine paprikash, and the Cubano. Their food is truly what sets them apart from other gastropubs in the area.
