I am an admitted coffee geek and seeker of the perfect cup. Sonoma County doesn't realize what it has with this gem of a coffee house. San Francisco doesn't have anything that compares to this.
You'd be hard pressed to find better coffee anywhere in the country. That's not just my opinion, go to coffeereview.com (the world's leading coffee-buying guide) and check out the reviews of Flying Goat's coffees -- all the reviews of their coffees are in the high 80s or 90s. Their Espresso Ticino (my personal favorite -- I buy a pound every week) is the only espresso blend to score a perfect 10 for flavor! And I agree: it's perfect.
Also try their Nicaragua, Mrs Garland's Blend and their house-made granola.
The service is very good. Sometimes a bit curt when they're busy (which seems like always) but I can live with that if they keep making perfect cappuccino!
I don't often get a chance to sit down at the goat, but when I do I also have noticed some pretty amazing musical selctions being played. All around, a great place. Healdsburg's location as well.
