Georgio's Roastery is a small coffee shop in Huntington Station on Jericho Tpke about 100 yards west of Rt 110, close to Massa's pizza. Whether you're biggest coffee concerns are how your coffee tastes, supporting local businesses, or where your coffee comes from, this is a great little place.
Georgio was the coffee guy at the Fairway in Plainview for a long time and left to open his own shop.
His coffee is outstanding. I had been buying pretty expensive coffee from my favorite roaster in California, and his is better. Everyone has their individual taste for coffee, but he roasts his own on Long Island (he has a 3lb roaster in his shop but doesn't appear to roast his beans there) and has a nice selection of beans.
He has pictures of the farms from which he buys his beans, and pays his farmers a buck a pound more than Fair Trade. Remarkably, he's only charging about $8/pound for most of his coffees. (I'm actually a little concerned about the long term feasibility of this.)
Anyway, I hope some of you give him a try if you're in the area- he's a really good guy, runs the shop with his wife (who I think blends teas for the shop, but I'm not really a tea guy), and creates a really good product.
