Alright, so there aren't any stores in New York City, but there are more than a dozen in surrounding areas. Find the closest to you here.
Since this deal isn't easily accessible for everyone, I thought I'd tell you about the 3rd Cask Ale Festival at Chelsea Brewing Company which starts tonight and goes through Sunday. With no cover charge and cheap half/full pints, this is one of the most economical beer festivals you'll ever find. I've been to the first two and had an awesome time... and spent less than $20 while I drank the day away. Check out the details here.
