Union coffee is a cafe near Ari Soi 1 in Bangkok, at BTS Ari station on Phahonyothin Rd in Phaya Thai. It serves matcha lattes and hojicha lattes, and coffee is made either with condensed milk or with syrup. The shop sits under a large tree, so it stays relatively cool even at midday, and the matcha drinks can be taken out. The matcha latte can be ordered at 50% sweetness, and the hojicha latte unsweetened.
