Today in Harvard Square, head to the Harvard Bookstore Warehouse (not the one near Mr. Bartley’s Burgers. not the COOP but 14 Park St. in Somerville) for 15% off and get your cookbook fix. Q’s nuts and other local Somerville food folks will be there with treats should you get hungry while you browse the books.

Then grab the family and head to Danehy Park for fun, free hot dogs. (while the last) , bake sale and more.
