If you live in NYC, go to Stumptown. It's better than Blue Bottle and is one of the best roasts I've ever had.
harrumph... stumptown got bought out 6 months ago (although I haven't been there in a while - so I can't really comment), and blue bottle has some of the best roasts i've ever had

different tastes?
grumpy probably has my favorite espresso in the city (although they change it all the time, and it's one of the more expensive ones)
i'm always a fan of ecco, so Joe is my go to spot usually
