Beer on the Wall is a great local establishment and beer store in downtown Arlington Heights with a fantastic and outstanding selection of craft beers and spirits. It offers many rotating taps for sample pours, flights, and drafts, plus an awesome selection of cans and bottles sold as singles so you can mix and match. There is a nice little outdoor seating area. The staff is friendly, helpful, and attentive. It is a great place to unwind, though it can get busy. The space is not big and has limited food, but you can bring your own food or snacks.
