If you scored tickets to an upcoming show at House of Blues, head to Eventide beforehand to snag a deal on oysters – the Fenway spot is offering a special promotion for concert-goers. Just show your ticket stub (virtual or paper, if you’re old school) and a dozen freshly-shucked, briny little treats can be yours for just 12 bucks. They’ll make a nice precursor to the show or to additional eats like Eventide’s iconic brown butter lobster roll or maybe some clam chowder or Jonah crab toast (there’s also a cheeseburger and a fried chicken katsu sandwich on the menu if you’ve got less seafood-inclined friends in tow). There’s a limit of one dozen oysters per table but don’t let that stop you. Eventide is open Wednesday through Sunday from 12:00-9:00pm so plan accordingly and just be sure to leave yourself enough time to eat all the things.
