SINGLE LANE Specialty Coffee is a small specialty coffee cafe in an alley five minutes from Phra Khanong Station in Bangkok. It serves iced black coffee, iced latte, flat white, and a tuna melt made with buttery sourdough and jalapenos. The interior is a narrow, long corridor, which suits one person focusing on work, and Korean music plays in the background. Seating and drink sizes are limited, so it does not fit groups.
