Petit Soleil is a cafe selling coffee and desserts in an alley across from Kundaeng Kuay Chap, near Khao San Road. It grinds beans to order for Thai coffee special drip, americano, matcha latte, affogato, and brownies. Inside the plant-lined entrance are an air-conditioned first floor and a second-floor terrace facing the Chao Phraya River, with seats that have power outlets. Both coffee bean varieties are on the acidic side.
