There's been a lot of coffee brewing in Chelsea lately, with the recent openings of branches of Think and Blue Bottle Coffee. Well, the java wars are going to get even hotter when Joe the Art of Coffee opens an outpost they are dubbing the "pro shop" on April 4. So, why do they get to call themselves pros? Well, of course there will be coffee for sale, brewed from a variety of beans including their primary roaster Ecco Caffe. They will also be selling all of the coffee making equipment that they use in the store, including the brewing machines and barista gear. In the back of the store, there will be a classroom and a tasting training lab for employees known as the headquarters. Hopefully this will all be enough to make it stand out in this caffeine-saturated area. Stay tuned for the opening on April 4 (131 West 21st St.; 212-924-7400).
