Kem Tràng Tiền is a long-established ice cream shop famous for traditional Hanoi flavors like coconut milk, mung bean, and taro, with affordable prices around $0.40 to $0.60 per popsicle. The shop offers a nostalgic atmosphere where locals often enjoy their ice cream standing, near Hoàn Kiếm Lake, making it a popular spot for casual dates and family outings. While many ice creams use natural, preservative-free ingredients and some vegan-friendly options like coconut popsicles are available, patrons should verify ingredients due to occasional dairy presence.
