If you’re in Harvard Square and looking for a lunch to keep you going, check out Tommy Doyle’s Irish Pub, 96 Winthrop St., where they’ve just initiated a lunch special: a housemade ½-pound Angus burger paired with a beer from the list. The deal runs Monday through Saturday, noon-4 PM. The kicker? It's just $9.99 (617-864-0655). P.S. There are other locations, but the offer is for Harvard Square only.
