Nana's Green Tea Guoco Tower is a matcha dessert cafe in Guoco Tower in Tanjong Pagar, Singapore. It serves a matcha ice cream cone and a signature green tea latte, and drinks come unsweetened by default, so you ask at the counter if you want sugar. On weekends, customers working on laptops or studying do not make the store especially crowded. On weekday afternoons it gets busy and a queue forms, leaving little room for seating.
