There’s book signings and then there’s book signings in which Gale Gand makes brunch for you. We strongly recommend the latter, and a rare chance these days to experience it will be Sunday, April 22 when she takes over the kitchen of her friends Dan and Steve at Hearty from 9 to 3. She’ll serve dishes from her latest book “Gale Gand’s Brunch” and you can get a copy and have it signed, too. For reservations, call 773-868-9866.
