East Coast Grill hosts a special addition of Hell Night in honor of Halloween – or Helloween, as they call it. Here’s how it works: reservations for any of three seatings (5:30, 7:30 and 9:30pm) for the Thursday, October 31st festivities will be available on one day and one day only – Saturday, October 19th. If you’re in the Inman Square area around 9:00am, you can just walk in and make reservations in person, otherwise you can start calling 617.491.6568 at 10:00am to get a table. They’ll be awarding prizes for best costume at each seating and keeping the party going into the wee hours (1:00am). Set a reminder for Saturday morning so you can secure your Helloween table or, if hotter-than-hell fare isn’t your thing, plan on popping in for the party.
