Lobster lovers rejoice, all weekend. The Rotary Club of Mystic celebrates its 23rd annual Lobster Days, Saturday through Monday, at Mystic Seaport.

There will be live music, discounted admission to the maritime museum and, of course, lobsters: $21 for a single dinner, $37 for a double. An adult can have a single dinner with museum admission for $36; a child, 6-17, can have it for $32. The event is the major annual fundraiser for the Rotary Club.

Mystic Seaport, which features four National Historic Landmark sailing ships, is located one mile south of exit 90 off Route 95. The festival is Saturday and Sunday, 11 a.m. to 4 p.m., and Monday, 11 a.m. to 3 p.m. For more information, call (888) 973-2767 or visit www.mysticseaport.org.
