Piccolo Backyard Picoroaster is the Phra Nakhon branch of a specialty coffee roaster, a coffee shop a short walk from Sam Yot MRT. It pulls medium-light roasted beans for drinks including the iced americano, using a La Pavoni lever espresso machine. The classic machine, in use since the 1970s, extracts coffee that is round and smooth and keeps the aroma. There is air conditioning, a restroom, and several tables.
