Set on the buzzing Keong Saik St, Kok Sen is easy to overlook as just another coffeeshop. Expect amazing Claypot Yong Tau Fu, Big Prawn Bee Hoon, and Black Pepper Beef with Bitter Gourd. This is one of those places you bring your parents to for a nice dinner, even though it's a humble little restaurant. Be prepared for slightly higher prices, it's totally worth it though!
