If you like beer and are going to be in the area, you need to be at Snallygaster. This self-described "gargantuan beer jamboree" is a one-day event featuring food, music, and over 150 carefully curated craft beers on tap. Tickets range from $10 to $50, with the latter including early access to the taps and 30 food + drink tickets. It's scheduled for 1-6 pm on October 19 at Union Market, and promises to be "an epic day of inimitable imbibery and monstrous merriment", but perhaps the best thing about it is the fact that your admission fee goes to help support the Arcadia Center for Sustainable Food & Agriculture.
