|What a place. Piazza dei Martiri is considered one of the most beautiful and bustling squares in all of Napoli, and who can argue? There is awesome people-watching here under the awnings over tables out front in the piazza: fashionable ladies in extra-large sunglasses, deal-making bankers in business suits, Carabinieri in full regalia stepping in for a brief espresso break. There's a monument in the center of the square - a column topped with a bronze statue depicting the Virtue of the Martyrs surrounded by four lion sculptures that each represent Neapolitan patriots who died during anti-Bourbon revolutions. Speaking of revolutions, the polizia across the piazza here are often out to keep an eye on demonstrations that frequently take place here. Entering the café itself, it showcases its namesake: an amazing collection of Neapolitan stovetop caffettiere adorning both the outside-facing display windows and the wide walls behind the service bar. It's almost like a museum to the Neapolitan coffee-maker. Despite it's well-heeled appearances, it's the only café we found in all of Napoli to outwardly promote the "caffè sospeso" project/movement, which oddly and suddenly blew up to became a global phenomenon in 2013. Also surprising given their clientele is the use of Kimbo coffee, which is decidedly more proletariat than what is carried by most noteworthy cafés in town. There are a number of fancy-looking tables inside, a "Ferrari Lounge", and tablecloths out on the piazza seating. Using two-group and three-group La San Marco lever machines, they pull shots with an even, medium brown crema. It has a full, robust flavor of some spice and a creamy texture and flavor. Served in La Caffetiera-logo IPA cups (co-branded Kimbo) for just ?1 at the bar, though table service gets served with glass and metal cups. Their milk-frothing may not be very elegant, but the micro-bubbles are somewhat even and have a good texture. Rated two tazzine and two chicchi in the 2014 Bar d'Italia.
