It's that time of year again when pumpkins fill the back wall of Annenberg, Starbucks brings back the Pumpkin Spice Latte, and students flock to The Garment District. The abundance of free treats and fun of the holiday can be overwhelming. But luckily, Flyby is here to help with a guide to the Halloween activates around Harvard Square.

Halloween Treats:

What would Halloween be without the plethora of pumpkin-flavored food and drink? Grafton Street Pub's Saturday night party features music until 2 a.m. and a special Halloween menu featuring pumpkin fritters, true blood martinis, hot pumpkin cider, and southern tier pumpkin. On Tuesday night, Brattle Theater opens its Haunted House of Pancakes. For $5, watch an exposition of pancake films, along with a complimentary stack. And on Halloween, head to UpStairs on the Square for a harvest dinner made with all vegan ingredients.

Costume Contests:

If you think you've got a particularly creative costume, why not give the catwalk a try? This Saturday, The Donkey Show is hosting a Halloween disco party, which includes party favors for all guests and prizes for unique and disco-themed costumes. And on Halloween night, UpStairs on the Square's annual party includes a special menu and "Scary-oke", not to mention a prize for the winner of the costume contest.
