I personally know Frosty and many other baristas around Guate, most of them positioned in the top 6 best (including the world's best barista 2012). I must say Frosty's coffee is among probably the best coffee guatemala has to offer, competing against Teco (Injerto Café). I've been influenced by Frosty's coffee, not only in desiring a cup of coffee every day, but to include him in one of my books (Despondency) which takes place in Antigua. I recommend this coffee place above all and, if you can, cask Frosty to prepare you one of his renown coffee espresso shots with Special Honey (bees that make honey only out of citrus flowers).
