Café Comunión was the only shop I found serving quality coffee in San Juan. I spoke with Abner Roldán, the shop owner, who currently happens to have his face on the cover of Barista Magazine. He's the Puerto Rico Latte art champion two years running, and he really knows his coffee. I almost never order a latte, but I wanted to see Abner work his magic, and it was spot on. My espresso + pourover were both delicious, as well. They raised over $5000 to keep the shop running after hurricane Maria, and it seems to be back to perfection considering the carnage at the very next shop over (last photo).
Enjoy the photos of the coffee - and stop back to the site again soon.
