Street Fourth Burger & Coffee Roaster is a restaurant on Samsen Soi 4 in the Khaosan area of Bangkok, serving Australian beef burgers and coffee roasted on site. It grills dry-aged beef patties and serves them with fries or onion rings, and also offers a guacamole burger and a chicken burger. The coffee is roasted in-house, with beans from several countries including Guatemala Huehuetenango, and the air conditioning is strong and the space is quiet. The buns are thin and the burgers are small, so one may not be enough.
