With the "Legal Sea Foods Oyster Festival" coming to a close, the Burlington location at the Burlington Mall will host the finale dinner – "Mollusk Mania & Aw Shucks" – tonight from 6–7:30 PM. Guests will be treated to an exclusive tutorial on the mollusks while enjoying raw and prepared oysters “by the bushel." One lucky winner will take home the jewel of all oysters: a cultured strand of pearls, courtesy of DePrisco Jewelers, worth $1,250 (dinner costs $45 per person, including tax and gratuity; 617-530-9195).
