Of all the flightless birds, chickens remain America’s favorite kind to eat, narrowly beating out penguins, kiwis, and Larry Bird. Make bird the word with today's Groupon: for $10, you get $20 worth of comfort fare at Mr. Wonderful's Chicken & Waffles in Warrensville Heights.

Mr. Wonderful's veteran chefs batter and fry a menu's worth of soul fare, including crisp chicken and fish. A variety of chicken and waffle meals ($6.99–$12.99) star boneless or bone-in poultry, drizzled in a signature glaze that underscores the duo's complementary tastes, textures, and zodiac signs. Satisfy seafood hankerings with a shrimp po boy slathered in tangy sauce ($5.99) or a fried-catfish dinner accompanied by a duo of hearty sides, such as candied yams, slow-cooked greens, and creamy mac 'n' cheese ($10.99). A choice of more than 10 stuffed baked potatoes ($4.99–$11.99) transforms the humdrum spud into a tableside celebrity, and the restaurant's family meals ($8.99–$69) supply clans with the energy to tackle overdue tasks such as cleaning the basement or sewing matching sweater vests by hand.
