Koki Tamagoyaki at the basement of Raffles City Shopping Centre is the first kiosk in Singapore to specialize in tamagoyaki (to my knowledge). There are various toppings and you can add Mushroom rice to make it a meal. Koki Tamagoyaki also sells Shuu by Koki, a Japanese choux puff that is available in 5 flavors.
