To celebrate its 67th season serving up hot dogs, hamburgers, lobster rolls, and other goodies on Castle Island, Sullivan’s is selling its classic hot dogs for half price. This deal is on until Friday, March 2.

If you go, expect longer lines than usual. Sullivan’s is a popular Boston institution, and this special is making it even hotter.

For those unfamiliar with this area, the address for Sullivan’s is 2080 William J. Day Blvd. in South Boston (called “Southie” by the locals). Hours are daily, 8:30 a.m. until dusk. The breakfast menu is available from 8:30 to 10:30 a.m., and the lunch and dinner menu starts at 10 a.m.
