This is not, repeat, not an April Fool's joke.



In honor of Opening Day (Friday for the Cubs; April 7 for the White Sox), four Johnny Rockets locations will be offering $1 Chicago-style hot dogs (regularly $2.49) all day long on April 1 and 7. Have one, have four. There's no official limit.



Participating locations are 177 N. State St. and 30 N. LaSalle St. in Chicago, and in the suburbs, 623 E. Boughton Rd., Bolingbrook, and 2835 Showplace Drive, Naperville.



The city locations open at 10 a.m.; suburban stores open at 11 a.m.



If that's not a good enough deal, South Water Kitchen (225 N. Wabash Ave., 312-236-9300) will be passing out complimentary hot dogs from 5-7 p.m. on Friday.



Regularly priced at $8 on the restaurant's Tavern menu, these nontraditional sausages include a Bayou Dog (alligator andouille sausage with remoulade), a Deep Sea Dog (tuna sausage, tarragon slaw) and Veggie Dog (portobello mushrooms, caramelized onions) in addition to an all-beef Chicago dog. Kettle chips included.
