It might very well be the last rooftop party of the year, and it’s one you won’t want to miss. Legal Harborside is hosting their annual Mollusk Mania from 1:30-3:00pm on Sunday, October 4th, as part of Legal Seafoods’ month-long, citywide Oyster Festival. Tickets include access to the raw bar with eight varieties of oysters, a How to Shuck an Oyster station, and, of course, beautiful views of Boston Harbor. For diehard bivalve fans, shell out for VIP admission, which will get you a half hour head start (at 1:00pm) and four tickets redeemable for appetizers like baked oysters, pickled oysters, grilled oysters, or oyster sliders. General Admission tickets are $55 and VIPs are $65—both sell out fast, so click here to get yours now.
