Though charcoal drawing was once the dominant artistic medium in America, precious few masterworks survived the realization that those early portraits could be crumpled up and used to smoke delicious stacks of ribs. Honor forgotten artists with today’s Groupon: for $20, you get $40 worth of casual American fare at Don & Charlie's in Scottsdale.

The cooks at Don & Charlie's, which earned the New Times Phoenix's Best Ribs award in 2009, have plated Chicago-style chophouse steaks, seafood, and barbecue since 1981. The dinner menu boasts award-winning barbecue baby back ribs ($17.95 for a half slab) and a macadamia-nut-armored fillet of halibut, which honorably fights battles with grumbling tummies alongside sharp-shooting lemon-butter sauce ($26.95). Diners can choose one of 10 gourmet burgers from the burger bar menu, which is stocked with such selections as the Blue Royale, adorned with a regal helping of blue cheese and a crown of crisp onion strings ($11.95). The six-by-six menu—available from 5 p.m. to 6 p.m. Monday through Friday—is populated by discounted dishes such as a tender 6"x6" prime rib, which stands ready for luxurious dips in au jus followed by exhilarating belly flops in a creamy horseradish sauce ($19.95).

Walls decked out in athletic memorabilia and more than 700 signed baseballs enthrall hungry eyes as families relax and debate the difference between then and than in the casual dining room.
