If you are looking for the best Green Tea shake in town - head out to Dimsum 'n Dumpling in Greenhills Shoppesville and order their Green Tea Shake. It is not made of powder ( which is what you get when you order from Starbucks ). They actually use actual Green Tea, put milk in it and then place it in a blender.
Although the restaurant is called Dimsum 'n Dumpling - they actually serve dishes other than Dimsum and Dumplings. We ordered Korean Barbecue Beef toppings and Lapu Lapu fillet with Garlic sauce. They're good dishes and are great options when you're tired and hungry after the marathon shopping you would have done in the Greenhills shops.
