Heap Seng Leong Coffeeshop is a traditional kopitiam near Jalan Sultan in Kampong Glam, Singapore, serving kaya toast and coffee. The bread is toasted over charcoal and served with coffee gu yu with butter and soft-boiled eggs. The shop has been running since 1974 and is now run by the founder's son as a second-generation business. The cooking area and dishware handling are rough, so those sensitive to hygiene should avoid it.
